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.

SKU: G926173
Provenance
Kingman, Arizona
Characteristics
Mined in the Mineral Park district of northwestern Arizona, Kingman is among the most storied and prolific turquoise sources in the American Southwest. Its signature bright, sky-blue color — often laced with black, brown, or silvery pyrite matrix — has made it a benchmark stone for Native American silversmiths for generations, and "Kingman blue" remains a standard against which other turquoise is judged.
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.
