Physical properties
Polished, opaque blue-green stone with a vitreous-to-waxy luster. Mohs hardness 6–6.5; triclinic crystal structure and two cleavages near 90°. The pictured pendant’s identity is visual, not confirmed by testing.
Formation & geological history
Forms in potassium-rich granitic pegmatites as feldspar crystals; deposits range from Precambrian to much younger. Common localities include Colorado, Madagascar, Brazil, and Russia.
Uses & applications
Used for beads, cabochons, pendants, and decorative carvings; feldspar is also an important industrial mineral.
Geological facts
Its characteristic color comes from trace lead and water-related defects in the crystal structure, not copper.
Field identification & locations
Look for blue-green color, feldspar-like cleavage, and pale streaks; it is commonly sold polished, so appearance alone cannot rule out dyed material. This appears to be a shaped and polished pendant.
