Peach Aventurine

Quartz variety (SiO2 + Hematite/Goethite inclusions)

Hardness: 7 on Mohs scale; Color: Peach, salmon-orange, or pinkish-tan; Luster: Vitreous to waxy; Crystal Structure: Trigonal (often massive in this form); Cleavage: None (conchoidal fracture); Specific Gravity: 2.64-2.69. It often exhibits 'aventurescence' due to mineral inclusions.

Physical properties

Hardness: 7 on Mohs scale; Color: Peach, salmon-orange, or pinkish-tan; Luster: Vitreous to waxy; Crystal Structure: Trigonal (often massive in this form); Cleavage: None (conchoidal fracture); Specific Gravity: 2.64-2.69. It often exhibits 'aventurescence' due to mineral inclusions.

Formation & geological history

Formed in magmatic and metamorphic environments where quartz crystallizes with platy mineral inclusions like mica or hematite. The peach color specifically comes from inclusions of hematite or goethite. Found in rocks ranging from several hundred million to billions of years old.

Uses & applications

Primarily used for lapidary work, cabochons, tumbled stones, decorative ornaments, and by the metaphysical community as 'healing crystals.'

Geological facts

The name 'Aventurine' comes from the Italian 'a ventura,' meaning 'by chance,' originally referring to a type of glass created accidentally in the 18th century that resembled this natural stone.

Field identification & locations

Identify in the field by its distinct speckles or shimmering inclusions (aventurescence) that differentiate it from solid orange chalcedony. Commonly found in India, Brazil, and Russia. It will scratch glass but cannot be scratched by a steel blade.
