Abalone Mother of Pearl
Acrylic Resin
Aventurine Gemstone
Is iridescent mother-of-pearl harvested from certain saltwater mollusks. Paua shell is a variety of abalone.
Acrylic Resin is a  form of plastic which can be molded into a variety of shapes, including beads, components and findings.
Aventurine is a variety of translucent quartz with abundant small plate- or flake-shaped inclusions. Light entering the quartz strikes these inclusions and reflects from them. This produces a sparkly appearance known as "aventurescence."
When the inclusions are abundant and in a common orientation, their reflections can be eye-catching. This property, along with desirable colors, are what give aventurine its appeal as a gemstone. Aventurine is usually green, but also occurs in orange, yellow, red, pink, brown, white, gray, and blue.
Agate Banded
Alexandrite Gemstones
Amazonite Gemstone
Agate is a form of cryptocrystalline quartz. "Crypt" means hidden and the crystals 
making up agate are submicroscopic in size, definitely hidden from view.  Agate is 
the form of cryptocrystalline quartz that displays banding.  The bands may be thin 
or thick and may vary dramatically in color due to the presence of iron and 
manganese oxides.

Alexandrite is the highly regarded color changing variety of Chrysoberyl. The color of Alexandrite changes under different lighting conditions. If viewed in daylight, its color is greenish blue to dark yellow-green. If viewed in incandescent or candle light, its color is pink to red. Alexandrite is a very rare and highly valuable gemstone, and until recently was extremely difficult to obtain due to its rarity. However, new sources in Brazil and Tanzania have made this gemstone available and more mainstream on the gemstone market.

Amazonite is a trade name given to a light green to bright green variety of microcline feldspar. It has a Mohs hardness of 6 with perfect cleavage. It is often cut into cabochons for use in jewelry. Because it is relatively fragile, it is best used where it will not suffer abrasion or impact.

Amber Gemstone
Amethyst Gemstones
Ammolite Gemstone
Amber is a fossilized resin secreted by ancient trees. It usually has a yellowish to orangish-brown color but can be white, greenish, bluish or even black. It is easily cut and polished into bright, lightweight gems. Amber is an organic gem material.

Amethyst is a transparent variety of quartz that ranges from light lilac to deep purple in color. It is one of the most popular faceted gemstones and is sometimes cut en cabochon. It is found in deposits around the world.

Ammolite is a trade name used for iridescent ammonite shell material. It produces a bright flash of color that rivals fine opal and labradorite. All of the world's commercial Ammolite production comes from a small area in Alberta, Canada.

Apatite Gemstone
Aquamarine Rough Stone
Aragonite Rough Mineral
Apatite is a phosphate mineral that is mainly used in making fertilizer. It is also cut as a gemwhen found in clear crystals with attractive colors. It has a hardness of 5 on the Mohs scale and is brittle. It is a "collector's gem" rather than a jewelry gem.

Aquamarine is a blue variety of the mineral beryl. It receives its name from its seawater color. It ranges from a very light blue to a richly saturated blue, with the richer color being much more desired.

Aragonite is the main component of many organic substances, such as pearl and coral. The iridescent surface of pearl and mother-of-pearl is a layer of Aragonite secreted by mollusks and related invertebrates.
Some forms of Aragonite, especially the Flos Ferri variety, are very brittle and fragile and may easily break when touched. Such specimens need to be handled with utmost care to preserve them.

Azurite Rough
Actinolite Cat's Eye Gem
Almandite Garnet Gemstone
Azurite owes its name to its beautiful azure-blue color, which makes it a very popular and well-known mineral. It usually occurs with green Malachite, which may form green stains or specks on Azurite crystals or aggregates. The two minerals sometimes occur admixed or banded together, forming what is called "Azure-malachite" in the gem and mineral trades. A rarer Azurite mixture, known as "Bluebird", is Azurite mixed with dark red Cuprite. Azurite, "Azure-malachite", and "Bluebird" all have gem uses.

Actinolite (Cat's Eye)
Actinolite is green to grayish green mineral of the amphibole group found in metamorphic rocks. It sometimes has a fibrous texture that produces a strong cat's eye when cut en cabochon.

Almandine Garnet, also known as "almandite," is an iron-rich, red-to-purple garnet that is geologically very common and typically sells on the more affordable side of the garnet price range. For that reason, it is common in jewelry.

Ametrine Gem
Ammonite Shell
Andalusite Mineral Gemstone
Ametrine is a bicolor quartz that is half Amethyst and half Citrine. The color combination is caused by twinning. Mined commercially at only one mine in the world, located in eastern Bolivia.

Ammonite is an extinct group of marine invertebrate animals that produced a chambered shell. Their fossilized shells are often cut and used as an ornamental or jewelry stone. Agatized ammonites are a popular organic gemstone.

Andalusite is a metamorphic mineral that is strongly pleochroic and is underappreciated as a gem. A variety known as chiastolite has grains of graphite concentrated into a cross-shaped feature.

Andesite Mineral
Ant Hill Garnet Rough
Aurichalcite Crystals Rough
Andesite is a fine-grained, extrusive igneous rock composed mainly of plagioclase with other minerals such as hornblende, pyroxene, and biotite.

Ant Hill Garnet is a novelty gem that ants excavate, haul to the surface, and deposit on their ant hill. These red chrome pyrope garnets are often found on ant hills in parts of the southwestern USA.

Aurichalcite has a beautiful intense green-blue color. Most specimens are composed of tiny needles which may rub off and leave a blue residue of tiny crystals on a surface. Because of its fragility, specimens should be handled as little as possible and washing them with water is not recommended as this will ruin them.

Adhesive Glue for Jewelry Making
Adjustable Clasp
Alloy Charms
A liquid, semi-liquid, gel or film that adheres or bonds items together. E-6000® and G-S Hypo cement are adhesives.

Is a clasp with a short length of chain that allows the wearer to vary the necklace length by attaching the clasp into different links of the chain. It can include Hook-and-Eye and Lobster Claw Clasp styles.

A blend of elements to create a new metal, usually in order to add strength and durability. 
Argentium silver is an alloy of silver, copper and germanium.

Anklet Charm CHAIN
Annealing Metal
Antique Jewelry
A form of bracelet, usually chain, worn around the ankle. Anklets made of leather or fiber is increasingly popular.
Annealing is heating metal in order to activate, increase or change its strength, hardness, ductility and other traits.
​This is particularly useful for strengthening metal wire so it is softer to work with. Lampwork beads are also annealed to prevent the glass from shattering.

Antique is an item, regardless of quality, which was manufactured 100 or more years ago.

Antique Finish
Patina Jewelry Components
Aurora Borealis Rough Gemstone Crystals
(See also Antiqued) A patina created on metal beads and components that alters the surface colors and gives the appearance of age.

Metal beads and components which have a human-created patina which alters the surface colors and gives the appearance of age.

Named for the northern lights, aurora borealis is a term for crystal stones that have a highly iridescent surface. The effect is achieved by vapor blasting the facets of the lower part of the crystals with an invisible, micro thin metal sheet. This stone was created by Swarovski® in 1955 in collaboration with Christian Dior. Also known as AB, the term now refers to any highly iridescent surface.
Aurora Borealis 2X (AB2X) - The AB2X surface effect has two times the coating of the AB effect, covering the entire crystal. The iridescent rainbow effect is seen on all sides, producing the utmost sparkle.

Amulet Pendant
Art Deco Style Jewelry
Art Nouveau Jewelry Style
An Amulet is a pendant or charm that is worn for protective magical power.

Art Deco is a style characterized by angular geometric shapes, zigzags, bold colors, molded or faceted Czech glass beads, plastics (like celluloid or Bakelite) and chrome, unlike the curves of the previous era.   Also known as the geometric style that succeeded Edwardian jewelry beginning in the 1910's through the mid-1920's.  Colored stones were utilized more, and the opaque stones such as jade, onyx and coral were set in geometric shapes. Sleek animals such as Borzoi and Greyhound dogs were featured in some designs. It started out with relatively delicate designs, and progressed to a more bold and blocky style also called Art Moderne.

Art Nouveau is a style also known as "Victorian" or "Edwardian" consisting of fluid lines, floral and nature themes and natural colors. Also known for its flowing style with sinuous curves and naturalistic motifs that was popular from about 1895 to 1905. A common motif was a women's head with flowing hair. 

Arts and Crafts Jewelry Design
Aventurescence in Sunstone
Art and Crafts is a  design movement that began in the late 1800's as a rebellion against the mass-produced, machine made designs of questionable aesthetic value common in the late Victorian era. The designers felt that their work should look handmade, and therefore they often left hammer marks on the piece. Although pieces were made of gold, silver was more commonly used to emphasize the craftsmanship of the piece rather than the intrinsic value of the components. Stones were commonly less expensive.   Cabochon stones such as moonstone, mother or pearl, agate, amber, and enamel work were also used. 

An optical phenomenon that is seen as a flash of light as a gemstone is moved under a source of incident light. It is caused when many tiny platelet-shaped inclusions of a reflective mineral such as mica or copper or hematite are aligned with a common orientation within the gem material. Light entering the stone travels until it encounters one of these platelets and is then reflected. Because the platelets share a common orientation, they all reflect simultaneously and produce a quick flash of light as the stone is moved under the source of incident light. Reflections can also be seen if the light source is moved or the eye of the observer is moved. Aventurescence is the defining phenomenon of the gem material known as aventurine. It is also seen in sunstone and other materials.

Asterism is an optical phenomenon seen as intersecting lines of light that form a star-like figure just below the surface of a cabochon-cut gem. The phenomenon is called a "star" and is seen in gems such assapphire, ruby, enstatite, diopside, garnet, and spinel. The star is caused by reflections from a network of tiny parallel rod-shaped inclusions within the stone, known as a "silk." Each orientation of these parallel inclusions within the stone produces a single line on the surface of the stone. Four- and six-ray stars are most common.

Alabaster Rough
Apache Tears Rough
Alabaster is a name applied to varieties of two distinct minerals when used as a material: gypsum (a hydrous sulfate of calcium); and calcite, a carbonate of calcium, also known as onyx-marble, Egyptian alabaster, or Oriental alabaster.

"Apache Tears" is the popular term for rounded pebbles of obsidian or "obsidianites" composed of black or dark-colored natural volcanic glass, usually of rhyolite composition and bearing conchoidal fracture.

Backstitch - the running back stitch is a basic stitch often used to add beads to fabric. Both easy and durable, it can be used for a small embellishment or to cover an entire area with an elaborate design.

Bail Connectors
Bali Beads
A Bail is a finding that connects a pendant to a necklace. They come in different forms: some clip onto the pendant, some have mounts to glue the pendant to, and some attach to a ring on the pendant. The purpose is to hold the pendant flat when worn.
Sterling Silver beads made individually by hand in Bali, Indonesia.

A Bangle is a style of Bracelet consisting of a closed ring, usually metal or plastic and often brightly colored. Popular in the 1980s.

Baroque Jewelry
Barrel Beads
Barrel Clasp
Baroque is a design style of the 17th century characterized by elaborate ornamentation. An irregularly shaped bead, usually applied to pearls.

Barrel Bead refers to the shape of the bead - the bead can be made of any material such as metal, glass, wood, or plastic.

A Barrel Clasp is a common form of clasp, especially for necklaces. Can be hard to attach on bracelets without help, and often comes undone on anklets, so is best suited for necklaces.

Bead Caps
Bead Embroidery
A piece of jewelry used to tie hair back, available in many sizes and styles. Beadwork can be added to barrettes by working it onto fabric or leather first and then gluing or otherwise fastening the work to the barrette.

A Bead Cap is a metal bell or cap-shaped bead that goes next to a round bead, partly covering it. Often used on both sides of a bead to "frame" it.

Bead Embroidery is a technique for adding beads to fabric using traditional embroidery stitches. Beads can be used as embellishments on an incredible array of items from garments to shoes to home décor. 

Bead Tip
Beading Cone
Bead Weaving
A Bead Tip is another word for Callotte.

A Beading Cone is a fashionable way to end a multi-stranded necklace. The metal cone covers the ends of the strands, which are tied together in a knot inside the cone. 

Bead Weaving are techniques used to create jewelry, art objects and accessories. Weaving can be done on a loom, or simply using a needle and  thread . Bead weaving stitches that don’t require a loom are called "off-loom" techniques. 

Beggar Beads
Bell Cap
Beaded Bezel
Beggar Beads  are large, irregular or baroque semi-precious beads, often consisting of varieties of agate and/or quartz.

A Bell Cap  is made of solid metal rather than filigree, and often more oblong shaped to cap the end of tall narrow beads.

A  Bezel  is a setting where a stone is encircled with a metal rim. You can also make a "beaded bezel", for instance to surround the edges of a cabochon. Contrast with chaton setting.

Bib Necklace
Bicone Beads
Bolo Neck Tie
A Bib Necklace is a style of necklace that mimics a baby's bib, with a thick section on the chest and a thin  cord  going around the back of the neck.

A Bicone is a type of bead that looks like two pyramids or cones stuck together at their bases.

A Bolo can be made from a piece of cord, string, or braided leather fashioned into a necktie. It is fastened at the throat with decorative tips or an ornamental clasp. The two ends of the cord are threaded through the clasp so they are held in parallel, with the tips meeting each other evenly at the base. The clasp can be placed higher or lower in position on the chest, as the wearer prefers.

Bolt Ring
Braided Cords
Brass Charms and Jewelry
A Bolt Ring  is another name for a Spring Ring Clasp.

A Braid  is a form of a weave that includes strands of material folded over one another to make a thicker cord.  Wire, cord, or leather can be braided to make jewelry.

Brass  is an alloy of copper and zinc. Its malleability makes it easy to mold and it can also be worked "cold". Brass wire gives a distinctive color to pieces. Brass beads are sometimes plated with silver, gold or other precious metals. Different techniques are used to colorize brass beads including oxidation and polishing. The finest brass beads are imported from Africa or Asia.

Brick Stitch
Briolette Bead
Bugle Beads
A bead weaving stitch made with  seed beads  which looks like bricks stacked on top of each other. Brick Stitch is often used in triangular fringed earrings. Looks somewhat like peyote stitch sideways, although they are made differently.

A Briolette is a teardrop or pear-shaped bead or gemstone. It can be faceted or smooth. 

Bugle Beads are thin tubular shaped glass beads manufactured in lengths from 2 millimeters to 35 millimeters and a width of 1-2 mm. Bugle Beads can be threaded into jewelry or glued to fabric as decoration. These beads can be used to great effect in cascading style necklaces. Necklaces consisting purely of silver bugle beads are sometimes called liquid silver.

Bullion, French Wire or Gimp
Beryl Mineral Rough
Also known as French Wire or Gimp. This is a very finely coiled wire that forms a flexible tube like a spring. Bullion is used for finishing the ends of strung jewelry pieces. It is threaded over the cord to cover it where it is normally exposed, such as where the cord goes through the loop on the clasp at the ends of the piece. It gives a professional look and protects the bead cord from fraying from exposure. The downside is that it tends to wear rather quickly itself, so it is good for fancy jewelry that you don't wear often.

Bloodstone is a dark green variety of jasper that has numerous splashes of red color. These red splashes remind people of blood, and that is how the stone received its name.  It is found in different parts of the world, but most often in India. Its mineral name is heliotrope.

Beryl  is a most alluring and popular mineral. It occurs in a diversity of colors, and has several important gemstone varieties. The green variety, Emerald, is one of the most precious gems. Only green Beryl with a deep green color is called Emerald; light green Beryl is simply "Green Beryl" (or Heliodor if it has a yellowish color.)
Aquamarine, another important gemstone, is the greenish-blue to blue variety of Beryl. Green Beryl from certain localities can be heat treated to produce sky-blue Aquamarine. Other popular gem varieties of Beryl are the pink Morganite, and the yellow Heliodor and Golden Beryl. A deep red variety of Beryl, known as Red Beryl (or Bixbite) is extremely rare, and only comes from two localities in Utah. 
Pure Beryl is colorless. However, a wide range of impurities cause the diverse amount of colors and many varieties. The green color in Emerald is usually caused by traces of the element chromium, and the blue color of Aquamarine usually by iron.
Beryl is naturally transparent, however inclusions and impurities may make it opaque.

Black Moonstone
Black Opal
Bumblebee Agate
Black Moonstone is a gorgeous silky smooth stone with a velvety silver flash which plays across its surface when moved about in the light. Its color ranges from a dark slate grey to lighter shades of grey and sometimes reflects a red undertone. This dark color of Moonstone is a very unusual find; coming to us from Madagascar.
The name Moonstone is derived from this visual effect, or sheen, caused by light diffraction within its crystalline structure. Moonstone is composed of two feldspar species, Orthoclase and Albite. The two species are intermingled during formation. As the newly formed mineral cools, the intergrowth of Orthoclase and Albite separates into stacked, alternating layers. When light falls between these thin, flat layers, it scatters in many directions producing the phenomenon called “Adularescence” or “Chatoyancy”.

The name "black opal" is used for an opal with a black base color. This opal has blue play-of-color on a black base and is from Lightning Ridge, Australia. There are many types of opal.

Often called Bumblebee "Agate" or "Jasper," it is instead a rock formed at several volcanic vents in Indonesia. Some specimens reportedly contain arsenic. Although many cutters coat their stones with acrylic or resin, it is not recommended for use in jewelry or other uses that will place it in extended contact with your skin.

Named after the red-orange Kornel cherry, carnelian was believed by the Romans to be a stone of courage--able to shore up confidence and strength. In ancient Egypt, the stone was placed on mummies to assist the dead in their journey to the afterlife.
Carnelian is a variety of chalcedony and is a micro-crystalline quartz. It appears in a vibrant range of fire-orange reds to brown-reds and has a dull, waxy luster (as opposed to the vitreous quality of crystal quartzes such as amethyst). The reddish tints in the translucent stone are due to one of its ingredients: iron oxide.
Carnelian is found in India, Brazil and Uruguay. In India, the stone is treated with exposure to the sun that turns brownish tints to purer reds.

Citrine is the yellow to brownish-red variety of  the mineral Quartz. It is a widely used as a gemstone, and after Amethyst it is the most popular Quartz gem. Most Citrine is formed by heat treating purple Amethyst. Citrine may also be produced by heat-treating Smoky Quartz from certain localities. In some Amethyst deposits, the Amethyst has been partially or fully changed over to yellow Citrine by natural means of heating.

Natural Citrine, which is rare, is yellow to orange-yellow, and occurs in much lighter hues than the heat-treated material, which is dark orange-brown to reddish-brown. Virtually all heat-treated material has a reddish tint, whereas the natural specimens do not. Natural light yellow Citrine is often called "Lemon Quartz" on the gemstone market. Sometimes Citrine has a "smoky" hue to it, and can be borderlined between Citrine and Smoky Quartz, with either definition being correct.

Chrysocolla, the king of carbonate copper gemstones, is an alluring, vivid blue-green color and is often mistaken for turquoise because they share many visual similarities. It can often be found intermingled with malachite, turquoise and azurite, creating a wonderful mixed gemstone known as eilat stone. Legend has it that eilat stone was originally mined in King Solomon's mines in Africa. The rich, vibrant blue and green colors of chrysocolla are reminiscent of looking down upon the earth's surface from space.The name chrysocolla was first used to describe the stone by Theophrastus, a Greek philosopher and botanist, in 315 B.C. The word was derived from the Greek words chrysos, meaning gold, and kola, meaning glue, referencing the fact that chrysocolla was employed from the earliest times by goldsmiths as an ingredient for solder, called santerna by the Romans, to weld gold pieces together. This fancy gemstone has indeed inspired creativity in many artists, whether they were ancient goldsmiths using it as solder, Renaissance painters grinding it as pigment for paint or modern jewelry designer-artists including it within their florid designs.

Cats' Eye
Chrysoprase is the name of a translucent chalcedony that ranges in color between yellowish green and green. Its green color is usually caused by traces of nickel. Beautiful green chrysoprase is the second most valuable variety of chalcedony after gem silica.
The name "chrysoprase" is from the Greek words for "golden apple" or "golden leek." Today it is most often used for making beads and cabochons. Exceptional pieces of chrysoprase are sometimes cut into translucent faceted stones.
Chrysoprase as a gemstone was known to the ancient Greeks and Romans. A few pieces have been found among their artifacts, but its use in that time was not common. Chrysoprase first became a popular gem in Europe after deposits in Poland were discovered in the 1700s. Today, most chrysoprase is produced in Australia, but it is not widely used because supplies are limited.

Coral is a colonial organism that lives in warm, shallow marine waters and often develops reefs. It is a hard calcium carbonate material that can be cut or carved and polished into beautiful organic gems.

Also known as "chatoyance." An optical phenomenon in which a band of white light moves just under the surface of a cabochon-cut gemstone. The band is caused by light reflecting from parallel tubes, fibers, or other linear inclusions within the stone. The band moves back and forth beneath the surface of the stone as the stone is moved under a source of incident light, or as the source of the light is moved, or as the eye of the observer is moved. This phenomenon is characteristic ofchrysoberyl and tiger's-eye but is also seen in many other minerals including actinolite,tourmaline, apatite,beryl, sillimanite, and scapolite.

Crystal Opal
Cultured Pearls
Chinese Writing Stone Beads
Crystal Opal is a term used for transparent-to-translucent opal material that has a play-of-color within the stone. There are many types of opal.

Cultured Pearls are produced by placing small "seeds" of shell material within a live mussel. The mussel then coats the seed with successive layers of nacre to form a pearl. They are produced in a variety of shapes, determined in part by the shape of the seed.

Imagine beads made from an ancient stone wall filled with Chinese-looking hieroglyphics. That's the look of Chinese Writing Stone, a gemstone so beautifully mysterious even where it is found remains a mystery. There's no mystery to why more and more beaders are including this mauve/brown-colored gemstone in their jewelry, however. Chinese writing stone's earth tones and intriguing patterns make it a perfect complement to the mahoganys and red and yellow brown tones that are the new trend in accessory colors. Combine Chinese writing stone beads with black onyx, peridot, or citrine for jewelry that has a clear message written all over it. That message? You're a beader who knows how to create beautiful jewelry that's mysteriously ancient looking at the same time it's modern.

Chalcedony is a name used for any cryptocrystalline quartz such as agate, jasper, petrified wood, chrysoprase, bloodstone, onyx, sard, and carnelian. Some people reserve the name for a blue, unbanded, translucent material. The photo shows specimens of pink to purple chalcedony cut en cabochon.

Charoite is a light lavender to deep purple silicate mineral that has swirling, fibrous, or spotted patterns. It is a rare and relatively new gem material, discovered in Russia in 1978.

Chrysoberyl, a gem unrelated to "beryl," is an "extreme gem." It has a hardness of 8.5, a very high luster, and a high index of refraction. It is sometimes a color-change stone and is best known for its "cat's-eye."

Cane Glass
An undrilled gemstone with a smooth rounded top and a flat back. A cabochon is not faceted.

A Cameo is a carved gem or shell, in which the carved design stands out against a background of a different color.

Beads resembling old-fashioned candy sticks. Small canes of colored glass are fused together to create a larger rod, then coated with clear glass and fired. Most cane glass beads feature "lattichino"--thin white, clear or colored candy cane-like stripes. "Slicer" beads are smaller pieces, created from slices of cane glass.

Ceylon Beads
Cathedral Glass Beads
Jewelry Chain
Cathedral Glass Beads are made in the Czech Republic by pressing into a steel mold, coating with color then grinding and polishing every facet to reveal the base glass. The color coating remains on the ends, giving the appearance of bead caps.

Used to describe a particular finish in seed and bugle beads. The use of Ceylon before a color name indicates the addition of a luster coating or the inside coloring of an opalescent bead.

A Chain is a series of connected links, typically made of metal.

Chain Nose Pliers
Chain Tabs
A Chain Tab is a small, flat metal finding that is often hung on a piece of precious-metal jewelry and stamped as a "tag" that identifies the precious metal content.

A Chain Nose Pliers  is a pair of pliers with flat gripping surfaces, used to create reach into tight places, at difficult angles, to grip components, close jumprings, bend wire and stabilize a design while working. Available in both long-nose and short-nose varieties. Short-nose pliers offer more strength and stability and long-nose pliers give more reach.

Charms are small ornaments worn as pendants or on bracelets.

Chevron Beads
A Chatelaine is an ornamental chain, pin or clasp, usually worn at a woman's waist, to which trinkets, keys, a purse, or other articles are attached. Also used to refer to pins with two figures linked together by a chain.

A particular shape of cut glass or crystal, most commonly known as Swarovski crystal rhinestones. A chaton is a faceted, pavillion-shaped (pointed) bottom. Some chaton styles have the same point on top, while others have a smooth domed top (similar to cabochons) or a flat top (similar to faceted gemstones).

Chevron Beads are also called rosetta beads or star beads. This glass bead style was first created in Italy in the late 1400s. Chevron glass is composed of a varied number of consecutively-laid layers of colored glass. In between layers, the glass is pressed into a mold, to create the patterns within the beads. The glass is stretched to create a long tube, then cut into beads. Individual beads are then beveled or rounded at each end to reveal the chevron or star patterns in the glass. Only those beads with the internal structure exposed by beveling, cutting or grinding the end surfaces away are called Chevron Beads. All others are called rosetta or star beads.

Choker Necklace
Lobster Clasp
 Cloisonné Beads
A Choker is a tight-fitting necklace that is worn close to the base of the neck. May be plain or with pendants or ornamentation. Measures approximately 16 to 18 inches.

A fastener in jewelry-making, which connects two or more ends of a piece of jewelry together, allowing it to be worn. Clasps can be utilitarian and purely functional, or highly embellished design elements. Clasps are available in most materials, including metal, gemstone, bone, wood and more.

Cloisonne is an enamel with surface decorations set in hollows formed by strips of wire welded to a metal plate.

Coil Bead

Also called leaded crystal or leaded glass. A material used by adding small amounts of lead oxide to molten glass in order to change its properties. Crystal Glass has a higher density and increased light refraction, creating brilliant sparkling effects when cut.

(See also Pony Bead) A Crow Bead is a bead cut from a tube of glass or plastic, then tumbled and polished to smooth the edges. Used on the bottom of cornrow braids, in fringe and for some Native American styles.

Crystal Quartz
Cubic Zirconia
Crystal Quartz is naturally occurring quartz in its clear or colorless form.

A decorative sleeve closure used to fasten the two sides of a man's dress shirt (although some mens-style women's blouses will have this feature). Originally composed of two buttons on a short length of chain, a cuff link is now commonly created using a swivel-style finding. The finding is often hidden by a cabochon, carving or other small design motif.
