Irai was known for these superb, gorgeous calcites, and then the supply seemed to dry up. There were hardly any available at the Tucson show, and they were overpriced, so we bought none. Then, to our surprise, we found this wonderful cache of new specimens with one dealer at the small Spring Denver Show, and cherry-picked all the best ones. Unlike in the past, the calcites in this batch showed all sorts of different forms - all of them beautiful. This one is absolutely unique as far as I know - I surely did not see any others like it. It is a single HUGE, columnar crystal with stepped growth - SO unlike the original small spiky Irai calcites which came to be thought of as characteristic of the mine. 11.9 x 5.7 x 5.3cm
