Gold Quartz 12.5×4 mm Stone/Diamond 14k White Gold Post Earrings Gold Bearing Quartz is a natural gemstone that is usually mined deep underground. Finding snowy white quartz with visible veins of pure gold is extremely difficult. Most of the time, gold mined in quartz is found in microscopic amounts, not at all visible. Because of the veining of the gold, each piece of jewelry is one of a kind! We make this stone into wonderful pieces for both men and women, rings, bracelets, earrings, cuff links, and anything else you might imagine. We can even design a custom piece for you.
