Formation & geological history
Formed in igneous, metamorphic, and sedimentary rocks. Common environments include hydrothermal veins and pegmatites.
Uses & applications
Used in jewelry, carvings, and ornamental objects. Also popular among collectors.
Geological facts
Aventurine is known for its sparkling effect called aventurescence, caused by platy inclusions of mica or other minerals.
Field identification & locations
Identify by its green color and sparkling inclusions. Commonly found in India, Brazil, and Russia. Tips for collectors: Look for pieces with strong aventurescence.
