This elegant 14k yellow gold freeform ring holds a beautiful piece of Gold in Quartz, accented by three round channel set diamonds. Measures 13mm at widest point and shank is 2.5mm. 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 it’s own certificate of authenticity and a 10 year guarantee from the manufacturer.
