WHITE GOLD: Gold is a precious metal which is naturally quite soft. To give it a white color and increase its strength, gold is alloyed with white metals, such as silver and/or palladium, and often plated with rhodium. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural gold.

FILIGREE: a term for gold or silver wire that has been twisted into patterns and soldered in place. Modern stamping techniques can replicate the decorative appeal of this ancient artform.

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.

CITRINE: A member of the quartz family, citrine symbolizes cheerfulness and prosperity. Its name is derived from the French word citron meaning lemon. This sunny stone comes in colors from lemon yellow to amber brown, with its coloring agent attributed to iron. Citrine is the birthstone for November.

CULTURED PEARLS: Likened to the moon, pearls have been valued for their luminous glow and natural beauty for thousands of years. Today, high-quality cultured freshwater pearls make pearl jewelry affordable to all. Pearl is the traditional birthstone for the month of June.
