Physical properties

Hardness: 7 on the Mohs scale; Color: Clear with red, reddish-brown, or hematite inclusions; Luster: Vitreous; Crystal Structure: Trigonal; Cleavage: None; Specific Gravity: 2.65

Formation & geological history

Formed in hydrothermal veins or pegmatites where quartz crystals grow alongside or over iron-rich minerals like hematite or goethite, occurring worldwide.

Uses & applications

Used primarily in jewelry making, ornamental carvings, and as a popular collectible specimen among crystal enthusiasts.

Geological facts

Also known as lepiochoroite quartz or strawberry quartz depending on the exact mineral inclusion, the striking red needles and plumes are trapped inside the clear quartz matrix during its growth.

Field identification & locations

Easily identified by transparent to translucent quartz bodies showcasing internal red phantoms, flakes, or needle-like inclusions of hematite. Commonly found in Madagascar and Brazil.
