A superb example of gold-in-quartz is highlighted by free-form 18k yellow gold in this magnificent necklace. Gold-in-quartz was born millions of years ago from water pushing molten gold up from the center of the earth. In an unusual and rare occurrence, this pure gold filled the veins of bright white, marble-quality quartz, creating gem-quality pieces. Specimens such as this have been found in extremely small quantities in only three places in the world. This large center piece hangs surrounded by beads of white agate, some accented with unique, stipple-technique 18k yellow gold jackets. One-of-a-kind.
