Undamaged sharp crystals of Colemanite. May be some minor chipping or missing crystals on the edges but the main specimen looks to be undamaged with the naked eye. This specimen was sitting out at Tucson and picked up some of Tucsons native soil which is highlighted by the camera lens. With my eye, The crystals looked more liked having smoky grey highlights. But definitely dirt |
