Parasymplesite - Sold

Parasymplesite is a hydrous iron arsenate mineral, isostructural with vivianite. Ito et al. (1954) described this species from the Kiura mine, Japan, a locality with many similarities to Ojuela. Sturman (1976) studied Ojuela parasymplesite, and noted a significant zinc content.

On this specimen, parasymplesite forms bladed crystals to 1 cm. The color is a slate gray-blue. The bladed crystals are tightly grouped on the specimen, almost like a vein filling. There is a 2.2 by 1.5 cm coverage of well formed crystals.
