Description

Here we have a single, well-formed, non-twinned crystal of orthoclase.

From old Dr. Krantz stock, comes with copy of antique label.
Ōmi was a historic province of Japan correlating to todays Shiga prefecture.

"Granite pegmatite district, mined for centuries for its feldspar for the local ceramic industry. Crystal pockets have been almost completely worked out by local mineral collectors, and many of the dumps are overgrown with forest, so not much of collector interest is left to find here." (cit. mindat)
