Modern style fuses with natural form in the creation of this piece. The oblong-shaped center Gold-in-Quartz stone is surrounded by a free-form 14k gold setting. 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. This highly durable material was formed when pure veins of gold were forced into quartz by hydrothermal 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.
