9dmpst ((PLATTNERITE on HYDROZINCITE)), $10 MINIMUM BID, Hidden Treasure Mine, Tooele County, Utah, 5 x 3 x 2 cm, Miniature | |
Here is an excellent specimen of black Plattnerite on what at first looks like Calcite, but is white and soft. So I believe the white is Hydrozincite. ex Phil and Pat Stevens collection. |
