Cancrinite is an unusual sodium calcium aluminosilicate carbonate hydrate which is sometimes termed a feldspathoid. Forming a richly coloured sulphur-orange, diamond-shaped wedge, 1.7 cm in length, within a grey-white miniature-sized feldspar matrix, this lovely Norwegian specimen is labelled as from Svensken quarry II on its accompanying Michael Kruse label, indicating its age - this quarry having long since been consumed by the much larger A/S Granit larvikite quarry. We don't often encounter specimens from this area, making this an unusual find. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
