Rosell Minerales

Groups of octaedral magnetite crystals, some in staggered growth, with an excellent luster, very well defined faces and edges. They are disposed on a matrix of microcline crystals.

Size: 5 x 4.6 x 3.3 cm.
Main crystal: 5 mm.

Fan-shaped aggregates of epidote crystals with an intense green color and luster. They are accompanied by hyaline quartz crystals and fine olive green actinolite needles. A different specimen from this classic Moroccan locality.

Size: 8,6 x 6,5 x 5,2 cm.
Main crystal: 2 cm.

A really interesting good size and gemmy fluorapatite crystal. We can observe perfectly the combination of the first and second order prisms; very sharp terminal faces, with first order hexagonal dipyramid. A specimen to enjoy crystallography and aesthetics.
Crystal shows excellent brilliance, transparence and a vivid yellow color with green tones. The specimen is from a Moroccan classic mine located in the Imilchil mountains area.

Size: 2.6 x 1.3 x 1.2 cm.
Found in ca. 2012.

Classic locality

Group of sharp fluorapatite crystals of good size showing parallel growth, an elongated prism with vertical striations, and multiple terminal faces truncated by the pinacoid. Good brilliance, translucent and a very distinctive greenish yellow color. They present numerous inclusions of flattened prismatic deep black crystals, also vertically striated and opaque. SEM-EDS analyses indicate that they probably belongs to the hornblende group, most likely magnesio-ferri-hornblende. We will send analysis to the buyer. A very aesthetic and aerial shape specimen.

Size: 7.0 x 3.0 x 3.0 cm.

Druse formed by a group of quartz var. amethyst crystals, showing defined faces and edges, from translucent to transparent. One has a small notch in its upper face. They are disposed on a matrix of feldspar, probably orthoclase, with prismatic crystals of green epidote and fibrous actinolite.

Size: 6.5 x 6.0 x 5.5 cm.

Group of prismatic arfvedsonite crystals, showing parallel growth, one of the predominant and elongated. With striated faces and polycrystalline terminal faces. Dark green color, near black, in a feldspar matrix with very small prismatic zircon orange crystals.

Size: 8.5 x 6.8 x 5.5 cm.
Main crystal: 40 x 28 mm.

A really interesting gemmy fluorapatite crystal. We can observe perfectly the combination of the first and second order prisms; very sharp terminal faces, with first order hexagonal dipyramid, truncated by the pinacoid. Crystal shows good brilliance, transparence and a yellow color with green tones. With some prismatic black inclusions (epidote?). The specimen is from a Moroccan classic mine located in the Imilchil mountains area.

Size: 6.1 x 4.1 x 4.0 cm.
Main crystal: 20 x 14 mm.

We have seen many gemmy fluorapatite crystals from Imilchil, with the classic prism and more or less developed dipyramid. In this specimen we have a fantastic complexity of facets for this Moroccan locality. There is an exquisite combination of dipyramids of first and second order, highly developed, and some prism faces. It reminds Alpine fluorapatite. With honey tones and on a matrix with small magnetite crystals. A very interesting rarity. Not more available...
