Antonio Leal Farm, Equador, Borborema mineral province, Rio Grande do Norte, Brazil
8.8 x 8.3 x 4.2 cm
3.5 x 3.3 x 1.7 in
A mass of hundreds of sparkly, white colored Bertrandite crystals. The Bertrandite pseudomorphed after an unidentified mineral which from the shape was likely either Muscovite or Albite. There are also Euclase crystals mixed with the Bertrandite crystals but it is difficulty distinguishing them apart.
Flaws: The crystals are not complete on the edges of the specimen. Otherwise, the crystals are in excellent condition.
