Physical properties

Hardness: 7 on Mohs scale; Color: Transparent to translucent with golden-brown or metallic shimmering inclusions; Luster: Vitreous to greasy; Crystal Structure: Trigonal

Formation & geological history

Formed in igneous or metamorphic environments where quartz crystallizes and incorporates tiny plate-like inclusions such as goethite, lepidocrocite, or hematite.

Uses & applications

Used primarily for making jewelry, cabochons, carved gemstones, and as a collector's specimen.

Geological facts

The glittering effect is known as aventurescence, which is caused by the reflection of light from minute, evenly distributed mineral flakes trapped inside the quartz matrix.

Field identification & locations

Easily identified by the distinctive sparkly metallic inclusions suspended within clear or milky quartz. Commonly sourced from India, Brazil, and Russia.
