“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. This very rare stone is cut into slabs, revealing the gold vein. They are then cut, shaped, polished and mounted into a 14 or 18k gold mounting. Because of the veining of the gold, each piece of jewelry is one of a kind! We make this rare stone into wonderful pieces for both men and women in rings, bracelets, earrings, cuff links, and anything else you might imagine.
