The Kingman mine in Mohave County, Arizona has operated continuously since the late nineteenth century, producing turquoise in a remarkable color range from sky blue to deep blue-green, with its spider-web matrix specimens ranking among the most valued turquoise in the world.
From its discovery in the copper-rich hills near Globe, Arizona in the 1920s to the mine's permanent closure in 2012, Sleeping Beauty turquoise has undergone a transformation from abundant commercial stone to one of the most coveted minerals in the gemological world, with prices increasing 300-400% since the final extraction.

Discover this exceptional Native American Earrings, handcrafted by Navajo (Diné) artisans, meticulously crafted in Sterling Silver. This remarkable piece showcases genuine Spiny Oyster, beautifully complemented by Gaspeite and Kingman Turquoise. The Spiny Oyster featured in this piece carries a rich heritage — Harvested from the warm waters of the Sea of Cortez off Baja California, Mexico. The shell ranges from deep red-orange to purple and has been traded into the Southwest for over a thousand years. Complementing the design, the Gaspeite adds its own story — Originally discovered in the Gaspé Peninsula of Quebec, Canada, this apple-green stone is now primarily mined in Western Australia. Its bright, fresh color has made it popular in contemporary Native American jewelry. Rounding out this composition, the Kingman Turquoise brings additional character — From the Kingman mine in northwestern Arizona, one of the oldest and largest turquoise mines in North America. Operating since the 1880s, it produces classic blue turquoise with distinctive white and black matrix. Available in size Post. The Navajo Nation spans 27,000 square miles across Arizona, New Mexico, and Utah, making it the largest Native American reservation. Navajo silversmiths learned their craft in the 1860s and developed iconic styles including squash blossom necklaces and concho belts. This piece bears the signature of artist Rick Tolino, a mark of authenticity and personal craftsmanship. Every piece at Humiovi is one-of-a-kind — once sold, it can never be replicated. Ships from our gallery in Sedona, Arizona.
SKU: 223996E
Cared for thoughtfully, a handcrafted piece is meant to last generations. A few essentials for this one:
Turquoise
A soft, porous stone — keep it dry and away from perfume, lotion, and household chemicals so its color stays true.
Sterling silver
Buff with a soft polishing cloth — leaving intentional oxidation intact — and store airtight to slow tarnish.
Last on, first off
Put your piece on after fragrance, lotion, and hairspray — and take it off before water, sleep, and sport.
Store with care
Keep each piece in its own soft pouch, away from direct sun and damp, so softer stones never meet harder ones.
