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.

I’ve added a small group of beautiful elbaite tourmaline specimens in this Stak Nala Tourmaline Update (click here). Since the 1980s, elbaite toumaline crystals from the pegmatites at Stak Nala, in Pakistan’s Northern Areas, have been known worldwide. Particularly distinctive and prized when associated with albite crystals, these tourmalines are usually colour-zoned, with dark green to black-appearing centre sections, with zones of green, and sometimes pink, blue or colourless zones at the terminations. Often, a closer inspection with strong light or a strong reflective background is needed to fully show these zones. The doubly-terminated crystals from Stak Nala are super examples of hemimorphism (the crystal forms present at one termination are different from those at the other termination). You’ll see that this update also includes one great lepidolite crystal.

I was fortunate to acquire these from a member of the family that mines them.
