With beautiful curves, this glamourous two tone 14k white and yellow gold ring holds a spectacular oval gold in quartz center stone. With contemporary grace, 16 round diamonds gently encircle the quartz, setting off the spectacular gold marbling. Total diamond weight is .24 carats and the ring measures 18mm 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.
