Physical properties

Formation & geological history

Forms when silica-rich fluids crystallize quartz containing dispersed chromium-bearing fuchsite mica, commonly in metamorphic rocks. The specimen’s exact geological age cannot be determined from the photograph.

Uses & applications

Used for carvings, beads, cabochons, decorative stone, and inexpensive lapidary material; it is also sold as a collector and ornamental mineral.

Geological facts

The green color and aventurescence result mainly from mica inclusions rather than green quartz itself. Similar-looking material may be dyed quartzite or other green minerals.

Field identification & locations

Identify it by its green, cloudy quartz body, hardness, and occasional glitter; glass scratches more easily. Common sources include India, Brazil, Russia, and Zimbabwe.
