This ring is made with AA-grade natural white druzy quartz cabochons - 10mmx8mm. Each stone is different in shade and size of crystals, because they are formed naturally.  Bijoux stacking rings are made by hand in our studio in Greensboro NC. They are made of 14k gold filled or sterling silver material, and are soldered, quenched, polished, and shaped by hand. Wear alone or stack with other rings!  Each of our gold Bijoux rings come in a ring box made specifically for storing and keeping your jewels safe.  These items are made to order, therefore have a longer turnaround time than the ready-to-ship items: they will be shipped within 5-10 business days of your order.
