This ring is as durable as it is handsome. Set with a mysterious midnight gold in quartz center stone and surrounded by genuine gold nuggeting, it is beautiful on and off the finger. Mounted in 14k gold, this ring measures approximately 12mm at its widest point. Less than 1% of the gold in the world is in the form of natural nuggets-nuggets that still remain represent a limited and diminishing resource, as most of them have either been mined or melted down. Nuggets are formed as a consequence of the concentration of gold by free flowing water. Every nugget is unique and aids in the creation of a beautiful and memorable piece 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. 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.
