This ring is as durable as it is handsome. Set with a midnight gold in quartz center stone and surrounded by natural gold nuggeting, it is beautiful on and off the finger. Less than 1% of the gold in the world is in the form of natural nuggets-nuggets that still remain represent a limited resource, as most of them have either been mined or melted down. Every nugget is unique and aids in the creation of beautiful pieces of jewelry. 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.
