Frequently asked questions
-
Is your turquoise real, or is it dyed howlite?
Turquoise is hydrated copper-aluminum phosphate. Dyed howlite and dyed magnesite are common imitations sold as "turquoise" in the broader bead trade — those are different minerals entirely, not turquoise. Treatment category (Natural, Stabilized, Composite / Reconstituted) should be disclosed — ask before buying if a strand doesn't specify treatment or mineral identity. -
What does "stabilized" turquoise mean — is it fake?
Stabilized turquoise is turquoise that has been infused with clear epoxy resin under pressure to harden the naturally porous stone for jewelry use. It's color-stable and the industry-standard treatment for the vast majority of bead-grade material. It's distinct from composite/reconstituted material, which is bonded particles rather than treated whole stone. -
What's the difference between Sleeping Beauty, Kingman, and Hubei turquoise?
Sleeping Beauty (Arizona, mine closed 2012) is pure even sky-blue with little or no matrix — scarce and supply-constrained. Kingman (Arizona, active) covers the full Arizona range from clear blue to deep blue with bold matrix. Hubei (China, active) is the dominant commercial bead source — typically blue to blue-green with rich veining, almost always stabilized. -
Will the color change over time?
Stabilized turquoise is color-stable and will look much the same in five years as it does today. Untreated natural turquoise can shift slowly over years from skin oil and chemical contact — some designers and collectors prize this aging; others want consistent color, in which case stabilized is the right pick. -
How do I tell if turquoise is real?
Practical tests include weight (real turquoise feels denser than plastic or resin), a fingernail scratch on an inconspicuous spot (howlite at Mohs 3.5 will scratch easily; turquoise at 5–6 will not), a hot-needle test (plastic imitation will smell of melting plastic), and an acetone swab (dyed material will release color). The most reliable signal is buying from a seller that discloses treatment and origin per SKU.
