9iddbts ((COLEMANITE)), $25 MINIMUM BID, Boron Open Pit Mine, Kern County, California, 5 x 5 x 4.5 cm, Miniature | |
Here is a spherical specimen covered with sharply terminated Colemanite crystals. Looks undamaged to me expecially with the naked eye. Bottom is flat or flattened so that it sets perfectly for showing 360 degress. ex Jim Minette |
