14kt yellow gold Vintage shiny bypass ring with lapis bullet ends, size 7.5. 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".
