Physical properties

Formation & geological history

Primary origin is metamorphic, where quartz recrystallizes under heat and pressure. The red color is caused by the inclusion of tiny plate-like minerals such as Hematite or Goethite during formation.

Uses & applications

Used extensively in lapidary work for cabochons, beads, and tumbled stones. Also popular in metaphysical circles and used as decorative architectural accents.

Geological facts

Unlike green aventurine which gets its color from Fuchsite mica, red aventurine gains its warm hue from iron oxide inclusions. It is a common 'tumble stone' used for rock tumbling hobbyists.

Field identification & locations

Identified by its distinctive grainy quartz texture combined with a shimmering reddish metallic luster. Commonly found in India, Brazil, Russia, and Tanzania. Look for internal sparkles when rotated under light.
