Physical properties

Formation & geological history

Formed in silica-rich igneous or metamorphic environments, commonly through hydrothermal processes; geological age is locality-dependent. The specimen has been tumbled and polished by human processing.

Uses & applications

Used as a lapidary stone, decorative pebble, jewelry component, and collectible. It is not suitable as a construction aggregate in this small polished form.

Geological facts

The orange-pink coloration may result from iron-bearing inclusions or coatings; true aventurine commonly shows glittering aventurescence from mica or hematite, which is not clearly visible here.

Field identification & locations

Look for glassy luster, translucency, and hardness sufficient to scratch glass; quartz typically lacks obvious cleavage. Common sources include Brazil, India, Madagascar, and China, but visual identification alone is uncertain.
