DEFINITION OF TERMS

• Alloy Combination of homogenized metals. Base metal mixed with precious ore to make it workable, harden it, or change its color
• Annealing metal Is a heat process whereby a metal is heated to a specific temperature/color and then allowed to cool slowly. This softens the metal which means it can be cut and shaped more easily.
• Antiquing Process of darkening recessed areas of to enhance the visibility of engraving
• Assay Process of establishing purity of gold, silver and other alloys
• Bail Connector at the top of a pendant. Enables pendant to hang from a chain or jumpring.
• Basse-taille (bass-tie) Technique of applying glass enamel to a metal surface that has been engraved deeply enough to hold the enamel when heated and has sides high enough to keep the enamel colors separate.
• Bezel setting The oldest and most basic gemstone setting, derived from the French word “Biseau” meaning chamfered. A collar style setting for a gemstone that offers more protection of softer or delicate minerals such as opal.
• Carre Setting Is where the stone is seated directly over a light well, and the stone is set by raising (hammering) four “spurs” with a “graver” tool.
• Carat Carat is a number from 1 to 24 that designates the percentage of pure gold in a sample of gold alloy. 24 carat represents pure gold. 18 carat indicates that 18/24 % or 75% of that sample is pure gold and the remainder is made up of metals other than gold
• Casting Method of shaping metal by melting and pouring into hollow molds. Less dense than wrought metals and requires additional polishing and finishing
• Channel setting Are primarily used to set faceted gemstones that are straight-sided, or quadrilateral in shape (baguette or princess cut)
• Electro-plating Electro chemical process of applying one metal to the surface of another.
• Engraving Process of decorating metal by gouging a design into its surface
• Gold Plating Is a method of depositing a thin layer of gold on the surface of other metal, most often copper or silver. It is often used in electronics, to provide a corrosion-resistant electrically conductive layer on copper, typically in electrical connectors and printed circuit boards.
• Harden Hardening is the process of making a jewelry component more stiff and permanent. This can be accomplished in a variety of ways including hammering and work hardening.
• Invisible setting Setting style where rows of square cut gemstones rest flush edge to edge; all within a metal border or frame, with no metal separating individual gems
• Jewelry Wire Jewelry wire is soft wire used to make jewelry. Jewelry wire can be brass, copper, gold, sterling silver, fine silver, gold-filled and/or gold and silver plated wire.

• Pave setting Is a tight grouping of identically sized stones laid across a flat, or convex surface, from the French word for “paved.” The stones are held in place using three to six raised beads per stone. Plating Is a surface covering in which a metal is deposited on a conductive surface. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, for radiation shielding, and for other purposes. Jewelry typically uses plating to give a silver or gold finish.
• Polishing Polishing is the process of smoothing the surface of an object. With jewelry wire polishing results in a shiny appearance and can remove minor tool marks or blemishes. Frequently polishing involves using a mildly abrasive polishing compound to remove a thin layer of material.
• Prong setting The most common variety for faceted gemstones is a prong setting, with either 3 or 4 prongs that hold the stone in place. This type of setting exposes the maximum amount of light to the sides and bottom (pavilion).
