Oyster Turquoise Jewelry in Sterling Silver  

Spiny Oyster and Turquoise: A Southwestern Composite Stone

Spiny oyster shell comes from the Spondylus species found in the Sea of Cortez and along the Baja California coast. Native American jewelers have used this shell material for centuries, prizing its natural color range from deep orange to coral red and occasional purple. When combined with turquoise from mines in the American Southwest, the resulting composite stone displays a striking color contrast. The turquoise component typically rates 5-6 on the Mohs hardness scale, while the shell material sits slightly softer at 3.5-4. Most composite oyster turquoise undergoes stabilization to improve durability for daily wear. This process strengthens the bond between materials and protects the finished stone from moisture damage. SilverRush Style has offered genuine stone jewelry since 2005. Every oyster turquoise piece ships in .925 sterling silver settings, and we provide free delivery anywhere in the United States. Our collection includes rings, pendants, earrings, and bracelets featuring this distinctive Southwestern composite.
