C. 1900 Vintage 23.7x17.5mm Agate Cameo and Cultured Seed Pearl Tassel Pin Pendant Necklace in 12kt Gold. 17.5"

12KT: Karat (abbreviated kt or K) is a unit that indicates the purity of gold in the metal. 12kt is 50% gold.

TEXTURED: A unique and varying finish with a tactile surface applied through various techniques, both by hand and with machinery.

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.

HINGED: A bale with a hinge. The hinge allows the pendant to be placed on and taken off a chain easily and without sliding. Ideal for putting pendants on chains that have large clasps.

AGATE: a variety of chalcedony, agate covers a rainbow spectrum of colors from black and gray to brown, pink, blue and yellow. Agate can be textured and exhibit a variegated layered stripe effect, which makes it a wonderful stone for carved cameos and beaded necklaces and bracelets.

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.

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.
