I’ve added some super specimens from Mount Malosa in this new Malawi Update (click here). These include excellent crystals of aegirine, arfvedsonite, smoky quartz with epididymite inclusions, microcline and zircon. Under shortwave ultraviolet light, the microcline is a striking deep pink-red colour, and the zircons exhibit various hues of yellow.

I’ve added some great specimens in this Mont Saint-Hilaire Update (click here). One of the world’s great mineral localities, with over 400 species, the quarry has been closed to collecting since 2007 (with isolated exceptions that have not produced specimens in any quantity). The specimens in this update are from finds dated from 1988 to 2007.

One of the most remarkable aspects of collecting at Mont Saint-Hilaire is that no two occurrences are the same – the mineralized zones and pockets are each different, with varied mineral assemblages and crystal habits. This selection of specimens represents several different finds, each of which was unique.
