Axinite-(Fe) with Danburite

#AH53932

SOLD

Availability: Sold

Locality: Colebrook Hill mine, Rosebery dist., Tasmania, Australia
Formula: Ca₄Fe²⁺₂Al₄[B₂Si₈O₃₀](OH)₂
Size: 7.5 x 8 x 7 cm - Sm Cabinet

Brown to purplish brown, lustrous, tabular crystals to 7mm. This is a great Axinite specimen with superb crystals. The original label with the specimen places the locality as Mt. Bischoff. I believe it is actually Colebrook based upon crystal forms and the association with Danburite, which are white to faint green crystals on the Axinite.
