Rosell Minerales

Group of well developed ettringite crystals showing a pseudohexagonal prism, rich in terminal faces. This specimen has a rare toasted honey tone for the species and it is believed to be due to exposure to sunlight out of the mine. This sample is accompanied by many sharp manganite crystals, very brilliant, some twinned, and with an intense black color. An unusual specimen for this classic mine collected in 1985.

Size: 2.3 x 2.2 x 1.4 cm.
