Fuchsite Rough Value Guide

Fuchsite Rough is a captivating variety of Muscovite mica, distinguished by its vibrant emerald-green hue derived from high chromium concentrations. Named after German mineralogist Johann Nepomuk von Fuchs, these Brazilian specimens are highly collectible for their distinct micaceous shimmer and historical use as both an ornamental stone and a pigment.

What affects the value of Fuchsite Rough?

• Intensity of the green color, with deeper chromium-saturated specimens commanding higher prices.
• The overall size and weight of the rough specimen, typically valued at approximately $30 for standard collector pieces.
• Structural integrity of the mica layers, as specimens that resist excessive crumbling are more desirable.
• Presence of unique mineral inclusions or crystal formations within the metamorphic rock matrix.

How to Identify Fuchsite Rough?

• Look for the characteristic micaceous structure, which appears as thin, shimmering layers or flakes that catch the light.
• Verify the intense green color, which should be consistent with chromium-rich Muscovite rather than surface dyes.
• Check for a pearly to vitreous luster on the surface of the raw, unpolished edges.
• Confirm the origin as Brazil, a primary source for high-quality metamorphic Fuchsite deposits.

History of Fuchsite Rough

Fuchsite is named after Johann Nepomuk von Fuchs, a German mineralogist. It is often found in metamorphic rocks and is prized for its shimmering green color, which comes from its chromium content. Historically, it has been used as an ornamental stone and in powdered form as a pigment. Many believe Fuchsite possesses healing properties, especially for matters of the heart and emotional balance.
