Italian Shell Seahorse Cameo Earrings in 18kt Gold Over Sterling

18KT: Karat (abbreviated kt or K) is a unit that indicates the purity of gold in the metal. 18kt is 75% gold. In Europe, 18K yellow gold is most favored and used in jewelry.

YELLOW GOLD: Gold is a precious metal with a natural yellow color. It is quite soft and often alloyed with other metals to increase its strength. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural 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."

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.

SHELL: A treasured gift of the sea, shell has been used for ornamentation since recorded time. Shell makes a classic choice for cameo designs and is often carved in relief to display a ladylike motif, presented in a frame of precious metal.

OVAL: An elliptical shape that resembles an egg.

CAMEO: A low relief carving where the carving is above the background layer. Usually carved in shell or stone to portray the profile of a woman.
