Rosell Minerales

Excellent specimen of this rare potassium and zirconium silicate. It shows rich aggregates of hexagonal crystals, transparent to translucent, with an excellent brilliance. Colourless to slightly violet.They are disposed on a matrix of acicular aegirine crystals with a very dark green color, almost black. The Kukisvumchorr Mountains are in the central part of the Khibiny Massif. The area has a very interesting mineralogy, notable for its nepheline syenites.
