Fuchsite (pronounced fooks-eyet or fuchsia) is a chromium-rich, apple-to-emerald green variety of muscovite mica. [1, 2]

 

Key Properties & Characteristics

  • Chemical Formula: K(Al,Cr)₃Si₃O₁₀(OH)₂ (trivalent chromium replaces aluminum to create its green color). [1, 2]

  • Color & Luster: Ranges from pale lime or mint green to deep emerald; features a vitreous to pearly, shimmering luster. [1, 2]

  • Hardness: Very soft, rating 2 to 2.5 on the Mohs scale. [1]

  • Cleavage: Perfect basal cleavage, easily peeling into thin, flexible sheets or platy aggregates. [1, 2]

  • Common Associations: Frequently found with quartz, kyanite, pyrite, or embedded with red ruby (known as ruby in fuchsite). [1, 2, 3]

  • Verdite: An opaque, dense, green ornamental rock composed mostly of massive fuchsite. [1, 2]

 

Origins & History

  • Discovery: Named in 1842 by Karl F. Emil von Schafhäutl in honor of the German chemist and mineralogist Johann Nepomuk von Fuchs. [1, 2]

  • Global Localities: Found worldwide, with notable deposits in Brazil, India, Russia, South Africa, and the United States. [1, 2, 3]

 

Uses & Popularity

  • Metaphysical & Healing: Often called the “Healer’s Stone” or associated with the heart chakra in crystal healing traditions, though these claims lack scientific backing.

  • Collector & Specimen Material: Sold as raw crystal chunks, tumbled pocket stones, or ruby-fuchsite carvings, typically ranging from $1 to $28 depending on size and polish.

  • Art & Pigment: Historically used as a shimmering green scatter material or pigment (available via specialty suppliers like Kremer Pigmente). [1, 2, 3]

 

Some Fuchsite specimens offer a satin green exterior, almost as if its color were painted on as a coat.

While Fuchsite is somewhat uncommon, it is not exceedingly rare, except in some circumstances.

 

Rarity and Form Factors

While the raw mineral itself is widely distributed, the degree of rarity depends heavily on the specific form, quality, and combination with other minerals: [1, 2]

_______________________________

Fuchsite Type / Variation

Availability & Rarity

Common Locations

Massive / Schist Fuchsite

Common: Readily available as flaky or scaly rock-forming green mica.

India, Brazil, Russia, South Africa, USA, and Madagascar

Ruby in Fuchsite

Uncommon to Moderate: Distinct green fuchsite matrix speckled with pink-to-red corundum (ruby).

Southern India

Green Aventurine (Fuchsite in Quartz)

Common: Fuchsite platelets suspended inside quartz make up popular, affordable green aventurine.

India, Brazil, Russia

Fuchsite Phantom / Inclusions in Quartz

Rare: Sharp, well-defined green crystal phantoms or inclusions trapped inside clear quartz points.

Madagascar and Sichuan, China

Well-Formed Individual Crystals

Very Rare: Fuchsite rarely forms distinct, large standalone crystals due to its soft, micaceous cleavage (Mohs hardness of 2 to 3).

Select pockets in Pakistan, Ethiopia, and European metamorphic belts
