Henmilite on Olshanskyite

LOCATION:

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

DESCRIPTION:

Many lustrous, rich royal-blue Henmilite (an exceptionally rare calcium copper boro-hydroxide) crystals to 3 mm are perched on contrasting matrix of white Calcite with small pockets of clear Olshanskyite (a rare calcium boro-hydroxide). The Fuka Mine is the type locality for both Henmilite and Olshanskyite. The Henmilite are euhedral, triclinic pinacoidal crystals. An unknown pale-blue earthy mineral is present on the Calcite and as a coating on some Henmilite crystals. A small patch of an unknown yellow mineral is also present. These specimens were found in 2004, and collecting thereafter was prohibited. This is a very richly covered specimen. If you don't have one of these, take advantage of this opportunity to get this one. They have essentially disappeared from the marketplace. No damage.
