18kt yellow gold 5/8" Vintage lapis disc drops on wires with textured frame. Lapis lazuli has been mined for over 6,000 years in regions such as Afghanistan and highly prized. The tiny "gold" flecks" sometimes present are pyrite ("fool's gold"). The ancient Egyptians ground it to use for eyeshadow. Renaissance & Baroque painters used it to make the brilliant blue paint pigment called "ultramarine".
