RM477   Vanadinite with barite
Pb₅(VO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

Group of vanadinite crystals showing a defined hexagonal shape, with very well defined faces and edges, intense red color. Good brilliance and some transparence, with internal reflections between red and orange. Main crystals size are remarkable. They are disposed very aerial on a lenticular barite crystal matrix. The presence of this barite matrix is highly appreciated by collectors and gives to the specimen a special aesthetics.

This sample was collected from one of these shafts where berber (amazigh) miners are working hard during months till they found a vug. This extended area, called Coud'a (Coudia), is located about half mile from well known ACF mine, but it is not the same mine.
The vanadinite veins mined in Coud'a, which are approximately 30 to 50 feet deep, are not the same than ACF mine and their particular mineralogy.

Size: 5,5 x 2,8 x 1,9 cm.
Main crystal: 9 x 8 mm.
Found in 01/2013.

RM491   Cobaltoan calcite

Druse of divergent prismatic cobaltoan calcite crystals showing rhombohedral terminal faces, which is not usual, perfectly defined and with good brilliance and translucent. The color varies between pink and tile red . Some of these crystals are partially covered on prism by small and brilliant minute calcite. This color zoning can be seen in the fractured area of the sample. From a Moroccan classic locality.

Size: 6,7 x 6,0 x 3,6 cm.
Main crystal: 5 x 5 mm.

RM462   Erithryte

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.
Sold
RM461   Erythrite

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.

RM363   Vanadinite with Coronadite and Goethite
Pb₅(VO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

Two generations of vanadinite crystals. A good-sized brilliant crystals, with echeloned growths and defined faces and edges. With good color yellow and peppered by deep black coronadite globular aggregates. Another generation shows small crystals (<1 mm) but with a nice luster, transparence, and yellowish tone. Both are on a matrix of goethite.

Size: 6,2 x 4,2 x 3,4 cm.
Main crystal: 7 x 6 mm

RM366   Vanadinite with Coronadite and Mottramite
Pb₅(VO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

In this excellent specimen we can observe different vanadinite crystals phases. The first is formed by botryoidal aggregates of small vanadinite crystals. Brilliant, translucent and with a yellow to greenish tones. On a second generation, we have huge size and brilliant crystals, with yellow to orange color, which show rounded faces and edges, one of them having a drop shape. One of the cavities of the goethite matrix is covered by very sharp and brilliant lanceolated prismatic crystals of mottramite. Also accompanied bybotryoidal coronadite. Novelty in SMM-2012.

Size: 9,5 x 5,2 x 4,0 cm.
Main crystal: 18 x 10 mm.

RM370   Vanadinite with Coronadite and Mottramite
Pb₅(VO₄)₃Cl
  -  8. Phosphates, arsenates and vanadates

A group of very curious yellowish vanadinite hexagonal crystals disposed on a layer of botryoidal coronadite acicular aggregates which are covering the goethite vugs. Accompanied by small but defined mottramite crystals forming clusters partially covering vanadinite crystals. They show a honey to brown color and dipyramidal faces and skeletal growths. A nice sample to be enjoyed on the display and under the microscope.

Size: 7,8 x 4,3 x 3,8 cm.
Main crystal: 6 x 5 mm.

RM341   Goethite-Hematite

A very aesthetic group of stalactitic goethite-hematite growth showing a very aerial disposition from this classic Moroccan locality. We can observe reddish radiated growths in fractured stalactites on the matrix.

Size: 8,8 x 8,3 x 7,1 cm.
Sold
RM137   Erythrite

The Bou Azzer's Erythrite is usually found as flattened tabular crystals but sometimes we can enjoy these needle like Erythrite specimens showing spherical aggregates formed by thin tabular crystals with an intense pink to purple color and excellent brilliance. A really good specimen from this Moroccan cobalt mine.

Size: 6,7 x 4,4 x 4,2 cm.
Main crystal: 9 x 9 mm. (aggr.)
