The rare mineral Naujakasite is a a hydrous aluminosilicate of sodium or of sodium and iron, usually containing calcium, potassium and manganese. This crude crystal is from Kvanefjeld Mountain within the Kuannersuit Plateau of the Ilímaussaq complex in Narsaq, Kujalleq, Greenland. Please note that in our reference to Greenland's geographical position, we have classed it as in Europe. However, this is correct politically, but geologically, Greenland is part of the North American continent, not Europe. The Naujakasite forms a large, mica included crystal of silvery-grey and lozenge or diamond-shape attached to an Arfvedsonite-rich matrix. Although the crystal does appear quite crude, even rock-like, because of it numerous inclusions, nevertheless it is a very fine example of this rare aluminosilicate species.
