RM555   Erythrite

Bou Azzer, Tazenakht, Ouarzazate, Souss-Massa-Draâ, Morocco

On a matrix covered by small quartz crystals, very bright, you have different groups of erythite crystals with a good size, showing the flattened prismatic shapes and intense color, typical for the species. A sample of quality and good size.

Size: 10,0 x 7,5 x 2,2 cm.
Main crystal: 33 x 17 mm.


RM461   Erythrite

Bou Azzer, Tazenakht, Ouarzazate, Souss-Massa-Draâ, Morocco

On a rich Co-As primary minerals matrix are disposed several groups of acicular crystals of erythrite forming colloquially called: hedgehog aggregates. They are partially covering the matrix, as isolated groups or like a velvet. The pink to fuchsia colors are remarkable and confers to the specimen an excellent aesthetics.

Size: 10,0 x 5,3 x 3,6 cm.
Main crystal: 5 mm. aggreg.


RM462   Erithryte

Bou Azzer, Tazenakht, Ouarzazate, Souss-Massa-Draâ, Morocco

On a heavy Co-As primary minerals matrix are disposed a rich group of acicular prismatic erythrite crystals. They form the usual globular aggregates but, in this specimen, disposition and this pink to orange color give to the specimen a different touch. A classic from this Moroccan cobalt locality.

Size: 6,0 x 5,8 x 5, 8 cm.
Main crystal: 7 mm. aggreg.


RM804   Erythrite with skutterudite

Bou Azzer, Tazenakht, Ouarzazate, Souss-Massa-Draâ, Morocco

In this specimen we have a very curious combination of erythrite forms. On the one hand, globular aggregates of this arsenate formed by needle like crystals with a velvet luster and a pale pink color. On the other hand, groups of lanceolated crystals with defined faces and edges, good transparence and deep purple color. All of them are disposed on a matrix with sharp cube octahedron skutterudite crystals. A fine specimen for this Moroccan locality.

Size: 6,0 x 4,3 x 3,2 cm.
Main crystal: 13 x 5 mm.
