Glassy melanterite. Width of the picture:15mm
Dimensions: 2" across. Melanterite efflorescence, from the breakdown of pyrite in the Ohio Shale. Almost a year after I collected the specimen (shown in the other image) the shale fell apart; the melanterite maintained its color and did not fall apart, so I removed what I could from the shale (July 2010).
