Aegirine mineral specimens from Sulitjelma, Norway, exhibiting dark green prismatic crystals within a white albeit or plagioclase feldspar matrix, the two contrasting colours make for an excellent eye catching specimen, available in various sizes and supplied in a tray with an information label.
Aegirine mineral specimen which exhibit dark green bladed crystals within a white matrix. Aegirine is a member of the clinopyroxene group of inosilicates (chain silicates), rich in sodium it is also known as Acmite. It was first described from a specimen in Rundemyr, Buskerud, Norway in 1835 & named after Aegir, the Scandinavian god of the sea. Aegirine commonly occurs in alkalic igneous rocks, nepheline syenites, carbonatites and pegmatites. Also in regionally metamorphosed schists, gneisses, and iron formations. These specimens were collected by our staff from Sulitjelma in Northern Norway and exhibit a striking bright white matrix with dark green monoclinic prismatic crystals set, the matrix being either albite or plagioclase feldspar. These samples are available in various optional sizes and will come supplied in a card tray with an information label.
