Physical properties

Hardness: 7 on Mohs scale; Color: Colorless/Transparent; Luster: Vitreous; Crystal System: Trigonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & geological history

Formed through the cooling of silica-rich magma or precipitation from hydrothermal veins. This specimen has been mechanically polished into a sphere from a natural crystal of indeterminate geological age (often millions of years old).

Uses & applications

Used in electronics (as oscillators), optics, glassmaking, and high-end interior decoration/collector spheres. It is also highly popular in metaphysical and crystal healing communities.

Geological facts

Quartz is one of the most abundant minerals in Earth's crust. For centuries, clear quartz was believed by some cultures to be permanently frozen ice. The term 'crystal' comes from the Greek word 'krystallos', meaning ice.

Field identification & locations

Identify by its ability to scratch glass, lack of air bubbles (which would indicate glass), and 'rainbow' internal fractures. Common locations include Brazil, Madagascar, and Arkansas (USA). For collectors, look for internal veils and phantoms.
