This is Pentagonite, emphasis on "tag." It is collected for its rarity. This sample comes from Wagholi Puna, India. To my knowledge, this is one of only two locations in the World where it is found. The other place, the "type location": Owyhee Dam, Lake Owyhee State Park, Malheur Co., Oregon, USA. It was discovered in the fall of 1960. Mr. and Mrs. Leslie Perrigo of Fruitland, Idaho found a blue mineral partly coating a large rock in a new roadcut near Owyhee Dam, Malheur County, Oregon. Nice find for a beautiful fall tree color walk!

I came to me in the capsule and tray shown above. I'll share the challengs to me in photographing it next time.
