Comments
Colourless lath-like xls to 0.75mm, or as green thin botryoidal crusts to a few cms sq. Hemimorphite from Esgair Fraith is found in much richer specimens, and maybe some of the best from mid-Wales. Drusey crystal masses to several cms were found 20-30 years ago (1980ish). Sometimes with a slight blue tint.
