CC5-RXHEpidote : {Ca2}{Al2Fe3+}(Si2O7)(SiO4)O(OH)

Fazenda Rubinho Pimenta claim, Capelinha, Minas Gerais, Brazil

This photo is a portion of a cabinet-sized cluster of epidote crystals, some over 5 cm long. For the most part, they are damaged and haphazardly stuck together like glued matchsticks. However, the interior of the cluster is undamaged and reveals extraordinary scenes such as this 8 mm field of view. The flat, horizontal planes are the surfaces of the much larger crystals comprising the cluster. The small, gemmy, perfectly-terminated epidotes are growing out of the larger crystals.
