I’ve added some excellent specimens in this Russia Update (click here). In particular, there are some super, transparent, colourless fluorites from Dal’negorsk, with crystals exhibiting up to five crystal forms. Among these area couple of great overgrowth and phantom pieces. These fluorite specimens are not new, I’ve kept an eye out for them in recent years and have acquired good ones when I’ve been able. This update also includes some great calcite specimens, with some fascinating crystal forms, and some fine datolite specimens with sharp crystals.

I’ve made no secret of my belief that excellent black crystals are very cool. But colour is great too, and the latest update has lots! The new DR Congo Update (click here) features some amazing hues of pink in beautiful specimens of cobaltoan dolomite from Katanga, some of which have green malachite in association. The update also includes a specimen with exquisite twinned calcite crystals from Mashamba West.
