Physical properties

Small polished, multicolored inlays set in metal. If genuine, turquoise is opaque, blue to green, Mohs 5–6, with a waxy luster; the red material cannot be reliably identified from the photo.

Formation & geological history

Turquoise forms through near-surface alteration of aluminum-rich rocks in arid environments, commonly in copper deposits. The earrings are crafted objects, and their geological ages and stone origins are unknown.

Uses & applications

Jewelry and collectible adornment; turquoise is also used in decorative inlay and beads.

Geological facts

The geometric inlay and metalwork are characteristic of Southwestern-style jewelry, but style alone does not verify maker, age, or stone authenticity.

Field identification & locations

The blue-green inlay may be turquoise, but dyed stone or synthetic material is also possible. Examine color and texture under magnification and seek testing for a confident identification; common turquoise sources include the southwestern United States, Iran, and China.
