Spessartine Garnet Specimen

Spessartine Garnet is a mineral species within the garnet group, specifically a manganese-aluminum silicate with the chemical formula Mn₃Al₂(SiO₄)₃. It is known for its striking orange to reddish-brown colors, ranging from vibrant "mandarin" orange to deep cinnamon hues.

Exceptional specimen featuring a large Spessartine Garnet with smaller Spessartines on Albite!

Key Properties:

Composition: A member of the garnet family (nesosilicate minerals). Manganese (Mn) gives it its distinctive orange color; iron (Fe) impurities can shift tones toward red-brown.
Chemical Formula: Mn₃Al₂(SiO₄)₃ (Manganese Aluminum Silicate)
Color: Ranges from bright orange ("mandarin garnet") to deep red-brown.
Hardness: 6.5–7.5 on the Mohs scale.
Luster: Vitreous (glass-like).
Crystal System: Isometric (typically dodecahedral or trapezohedral crystals).
Transparency: Transparent to translucent.

Sources/Locations:

Originally discovered in the Spessart Mountains (Bavaria, Germany).

Other notable sources:

Nigeria (bright orange "mandarin" spessartine).
Namibia, Mozambique, Brazil, Sri Lanka, Myanmar, and the USA (California, Colorado).

Spessartine garnet’s fiery color makes it a favorite among gem enthusiasts and jewelry designers!
