Turquoise is a dull blue-green mineral. It is a very rare and valuable mineral that has been used as a gem and decorative stone for thousands of years. It owes its popularity to its unusual color, which is caused by the addition of copper.

This luxury piece of jewelry is made of rhodium-plated silver. Rhodium plating or "antioxidation treatment" is a new way of surface treatment of jewelry. Silver oxidizes in the air, as a result it turns black, loses its luster, and its durability and quality decrease.
