Glossary of Terms

AURORA BOREALIS (AB) - A name for faceted glass beads that have an added iridescent coating.

AUSTRIAN CRYSTAL - An imitation, diamond look-alike. 32% lead oxide crystal made in Austria. May be colored.

BAIL - A metal triangle used to attach a bead or pendant to a necklace.

BAROQUE - An imitation pearl with an uneven shape or surface.

BIB - Multiple strands of stones, each shorter than the one below, nested together in one necklace.

CAMEO - A gemstone carved with a design that is usually two colors. The carving is raised above a contrasting colored background. Usually on a brooch showing a head in profile.

CARAT - The unit of weight (not a unit of size!) for a diamond or other stone. Equal to 200 milligrams or 1/5 of a gram. One carat is equal to 100 points. So 75 points weighs .75 carats. One carat of a dense stone will be smaller than one carat of a lighter stone. For example, a one carat sapphire is smaller than a one carat diamond.

CHOKER - A 14"-15" necklace that should nestle around the base of the neck.

CLARITY - Relative freedom from internal inclusions or surface blemishes.

CROWN - The upper portion of a gem or stone.

CRYSTALS - Man-made stones. The finest crystals are made in Austria. Austrian crystals are cut with facets like gemstones, but usually have a foil back to give the stone luster. Most often they are not used in an open setting.

CUBIC ZIRCONIA - A man-made crystal grown under tremendous heat. CZs are created using zirconium oxide melted at a constant temperature of more than 5000 degrees F. When cooled, this material forms a crystallized, diamond-hard, diamond-brilliant, cubic material. This material is then cut and polished to the exact specifications of gem quality diamonds. Developed by the Russians for their laser programs. Cubic zirconia reflects light like a diamond, and has a hardness very close to that of a diamond. While CZs will cut glass, only a diamond will scratch a CZ. The quality of the cut and size of the stone determine the value of the CZ. CZs weigh about 60% more than diamonds.

CUT - The cut determines the brilliance of a stone. If properly cut, the stone reflects light from one facet to another, to be dispersed through the top of the stone. Also called "make." Often, cut is used in describing the shape of the stone.

ENAMEL - A powdered glass coloring which is applied to a metal and heated to bond it together.

ENHANCER - A pendant attachment which opens to allow the pendant to be placed on pearls, beads or a chain.

ETERNITY RING - A type of ring set with a row of gemstones around the band. The stones are all of the same size and cut. The stones may be individually set in prongs or channel set. Also called an Anniversary band.

EURO-WIRES - A closure for pierced earrings. A curved wire passes through the ear and attaches to the backside of the earring.

FACET - One of the small, flat surfaces of a cut stone. Facets are of many shapes and sizes, depending on the cut of the stone.

FAUX - Imitation, false, fake. Sometimes abbreviate with f. as in f. pearl.

FILIGREE - A type of decoration in metal that is made with twisted or braided gold or silver wire. This forms an intricate, delicate design.

GIRDLE - The edge around a stone that separates the crown and pavilion.

GLASS PEARL - A man-made pearl that is made of glass and is coated with nacre, the same material that coats a genuine pearl. Glass pearls have a substantial feel and weight, and are cool to the touch, much like genuine pearls. Landau glass pearls are the finest man-made pearls.

GOLD - A precious metal, often mixed with other metals to give it strength and lessen the price. Yellow gold has alloys of copper, silver, and zinc. White gold has alloys of nickel copper and zinc. Pure gold is 24 karats and is too soft for use in most jewelry. Also see karats.

GOLD FILLED - Covered with layers of 14K or 18K gold joined to a base metal and rolled to the desired thickness. Usually abbreviated g.f. Lower in gold content than 10K.

GOLD PLATED OR GOLD TONE - Base metal covered with a thin layer of gold. The gold is plated onto the metal through electrolysis.

JACKET - A decorative addition to be worn with a stud earring. The jacket has a hole that the post of the stud is inserted into to hold both securely.

JET - A stone of petrified coal.

KARAT - The measure of fineness of gold. 24K is pure gold and is far too soft for use in most jewelry. Other metals are added for strength -- most commonly, silver, copper, nickel and zinc. 14K and 18K are most often used for jewelry. Using 24K as a basis, the karats signify what proportion of pure gold to alloy is in the piece. 18K has 18 parts gold and 6 parts other alloys. 18/24=75% Thus, 18k gold is approximately 75% gold. 18K has a darker color than 14K, which has zinc added for strength. 14K is approximately 60% pure gold (14/24). 9K has the same properties as 14K, but with additional metals added. It is approximately 40% pure gold. All gold is stamped with the number of karats. Europeans sometimes stamp with 420 (14K) or 750 (18K).
