Physical properties

Formation & geological history

Quartz forms in igneous, hydrothermal, and metamorphic environments; green color commonly comes from fuchsite inclusions in aventurine or heat treatment in prasiolite. Geological ages vary widely, and polishing/stringing are human processing.

Uses & applications

Used mainly for inexpensive jewelry, ornamental beads, and lapidary items; value depends on transparency, color, inclusions, and whether the material is natural or treated.

Geological facts

Aventurine typically shows glittery aventurescence from mica, while prasiolite is usually clearer and more uniform; this image alone cannot reliably distinguish them from dyed green quartz or glass.

Field identification & locations

Check for natural inclusions, aventurescence, cool density, and quartz hardness; glass may show bubbles and is softer. Common sources include Brazil, India, Russia, and Madagascar.
