Physical properties

Hardness: 7 (Quartz); Color: Milky white with green inclusions; Luster: Vitreous to waxy; Crystal Structure: Trigonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Formed in hydrothermal veins or metamorphic rocks. The green coloration comes from chromium-rich mica (Fuchsite) or chlorite minerals that were trapped during the quartz crystal growth, typically in Precambrian or Paleozoic environments.

Uses & applications

Used primarily as decorative lapidary material, for carving, in landscaping, and highly valued by metaphysical crystal collectors for its unique aesthetic and perceived energy.

Geological facts

When quartz is heavily included with Fuchsite, it is often called 'Green Aventurine.' This specific specimen shows the distinct transition between pure milky quartz and the host mineral inclusion layer.

Field identification & locations

Identify in the field by its hardness (will scratch glass) and its characteristic grainy or 'sugary' green texture alongside clear/white quartz. Common locations include Brazil, India, and parts of Russia.
