Sierra Bella turquoise comes from a new mine in the Sonora region of Mexico. It is characterized by a range of green tones – from deep forest green to vivid blue-green – often appearing within the same stone. Many pieces feature golden pyrite matrix flecks, giving the stones a distinctive metallic sparkle amid the green. This blend of rich greens and glittering inclusions makes Sierra Bella visually striking and unlike more traditional blue turquoises.
As a recently developed source, the Sierra Bella mine remains active but on a limited scale. Discovered in the 2010s, it has quickly caught the attention of Southwestern jewelers seeking fresh colors and textures. Stones are typically given a light stabilization (such as the Zachery process) to enhance hardness, so jewelers can confidently set Sierra Bella turquoise in rings, cuffs, or pendants without fear of color change. The unique coloration and modern provenance of Sierra Bella turquoise add a contemporary flair to Native American and Southwestern jewelry, making it a prized choice for collectors looking for something different.
