Copper Turquoise Rings in Sterling Silver  

What Makes Copper Turquoise Different From Regular Turquoise

Copper turquoise develops when copper-bearing solutions flow through turquoise during formation, leaving behind the characteristic reddish-brown to black veining called matrix. These matrix patterns vary from fine spider-webbing to bold geometric sections. The base turquoise ranges from pale sky blue to deep teal, while the copper content adds warm metallic undertones that shift in different lighting. Turquoise measures 5-6 on the Mohs hardness scale, suitable for rings worn with reasonable care. Most copper turquoise in today's market comes from mines in Arizona, Nevada, and Mexico, where geological conditions favor this mineral combination. The Bisbee and Kingman mines in Arizona have produced notable specimens with high copper content. We set these natural stones in .925 sterling silver, a standard that means 92.5% pure silver alloyed for durability. SilverRush Style has sold genuine stone jewelry since 2005.
