Comes with 14k gold-filled chain. Chain shown in photo not included. Photos are enlarged to display detail. “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, then cut, shaped, polished and mounted into a 14k gold mounting. 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 in rings, bracelets, earrings, cuff links, and anything else you might imagine. We can even design a custom piece for you.Stone size is 14×9 mm.
