Physical properties

Hardness: 7 (Mohs scale); Color: Neon green (concentrated in cracks); Luster: Vitreous; Crystal Structure: Trigonal (hexagonal prisms); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & geological history

Natural quartz crystals are harvested and then subjected to 'crackle-firing' or thermal shock to create internal fractures, which then allow green dye to seep into the crystal.

Uses & applications

Primarily used for decorative purposes, aquarium stones, inexpensive jewelry, and as a low-cost alternative for 'healing crystals' or 'fidget' stones.

Geological facts

Natural green quartz (Prasiolite) is actually a very pale, leek-green color and is quite rare; most 'emerald green' quartz crystals found in souvenir shops are artificially dyed using human-made pigments.

Field identification & locations

Identify in the field by looking for 'spider-web' patterns of darker green color concentrated in cracks. In a natural mineral, color is usually uniform or zoned, but not clustered in a fracture network.
