Rosell Minerales

Prismatic crystals of nepheline, associated with a matrix with black schorlomite (garnet group). Although nepheline is a fairly common rock-forming mineral in silica-poor igneous rocks, such as nephelitic syenites, well-formed crystals of this species are rare.

Size: 6.4 x 4.2 x 3.6 cm.
Main crystal: 14 mm.
Found in ±2009.

Very esthetic specimen of celestine from Morocco. It shows us a large group of prismatic crystals of this strontium sulphate, very well defined and faceted, and with an excellent transparence that allows us to see a soft bluish color. They are disposed on a compact matrix. This locality is northeast of Imilchil town.

Size: 10.2 x 9.5 x 6.8 cm.
Main crystal: 2 cm.

Very aesthetic aggregates of epidote crystals forming beams, with brilliance, defined and with this classic green color. They are disposed on the matrix with quartz crystals, forming very interesting concentric growths.

Size: 6.7 x 5.7 x 2.8 cm.
Main crystal: 9 mm.
