These three inlaid midnight gold in quartz stones could not have been better matched into this attractive 14k yellow gold ring. The shimmering gold marbling seems to flow with a mysterious allure across the length of this band (measures 9mm at widest point). Gold in Quartz is one of the world’s rarest forms of natural gold-much of it was destroyed in the early days of gold mining in order to extract the veins of embedded gold. Every stone is a one-of-a-kind created by nature. This highly durable material was formed when pure veins of gold were forced into quartz by hydrothemal pressure 1500-3000 feet below the earth’s surface. A truly unique, up-and-coming gemstone-no jewelry collection is complete without our 100% authentic, natural Gold in Quartz. Each purchase comes with its own certificate of authenticity and a 10 year guarantee from the manufacturer.
