Physical properties
Hardness of 6 on the Mohs scale, vibrant turquoise-green color, vitreous to pearly luster, and triclinic crystal system.

Uses & applications
Used mainly as a semiprecious gemstone in jewelry, for ornamental carvings, and as a collectible mineral specimen.
Geological facts
Its distinct green-blue color is caused by trace amounts of lead and water within the potassium feldspar lattice.
