Henmilite and Olshanskyite

Fuka Mine, Bitchu-Cho, near Takahashi, Kawakama Co., Okayama Prefecture,
Honshu, Japan

42.0 x 35.0 x 34.0 mm

Numerous lustrous, rich royal-blue Henmilite crystals to 4 mm are perched on contrasting matrix of botryoidal white Calcite with small patches of clear Olshanskyite, from the type locality for both Henmilite and Olshanskyite. The Henmilite are euhedral, triclinic pinacoidal crystals. Pale blue bands of an unknown mineral are present in the Calcite. These specimens were found in 2004, and collecting thereafter is prohibited. No damage. (Author: GneissWare)
