Physical properties
Rounded, polished, blue-green to green, with a fine glittery appearance; quartz has Mohs hardness 7, vitreous luster, and a trigonal crystal structure. The image alone cannot confirm the material or inclusions.
Formation & geological history
Aventurine forms when quartz grows with reflective mineral inclusions, commonly in metamorphic rocks; its age varies with the host deposit.
Uses & applications
Used for beads, cabochons, ornaments, and inexpensive jewelry or collectibles.
Geological facts
The subtle sparkles typical of aventurine are called aventurescence and come from reflective inclusions.
Field identification & locations
Common sources include India, Brazil, and Russia. Check for natural-looking, scattered sparkles and hardness, but glass or dyed materials can resemble it; identification from this photo is uncertain.
