C. 2000 Vintage David Yurman 3.50 ct. t.w. Peridot Earrings in Sterling Silver with 14kt Yellow Gold

STERLING SILVER: Also known as "Standard Silver," sterling silver is silver alloyed with other metals to increase the hardness and durability. Generally, sterling is 92.5% silver and 7.5% other metals. Some sterling silver jewelry is plated with 14kt-18kt gold and referred to as "vermeil," or "gold over sterling."

14KT: Karat (abbreviated kt or K) is a unit that indicates the purity of gold in the metal. 14kt is 58.33% gold. In the United States, 14K yellow gold is most favored and used in jewelry.

CLIP/POST: An earring with a post insert and a clip mechanism to hold it in place. The post can be removed by a jeweler to convert the earrings to clip-on.

PERIDOT: the birthstone of the month of August, peridot is only found in one color: green. Historians are now convinced that some, if not all, of the emeralds that Cleopatra was famous for wearing were not actually emeralds but deep green peridot stones from Egypt.

HEART: A shape that takes the form of a heart symbol, with two curved sections at the top and a point at the bottom.
