TWO-TONE GOLD: Gold is a precious metal which is often alloyed with other metals to increase strength and create different colors. A two-tone gold piece includes two colors of gold: yellow, rose, white, or gunmetal-finished gold. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural gold.
POLISHED: A buffed-out finish used to produce a mirror-like shine.
ENAMEL: Enamel is a glass-like colored coating which is applied or "painted" over the surface of a piece of metal, ceramic or glass. Enamel is made from powdered glass or an epoxy resin material.
REVOLVER: A safety that conceals the point of a pin and keeps it in place with a revolving lever mechanism.
Diamond: The hardest and most brilliant of all gemstones, a diamond can make the heart race with its pure and fiery spark. An ancient symbol of love, a diamond is the preferred gemstone for tokens of affection, such as rings, earrings, necklaces and bracelets. Diamond is the birthstone for April.
