Apparently all words associated with the colour blue, and you can add to that ‘rare’ and ‘desirable’, because what we have here is tanzanite; beautiful, serene, periwinkle blue. New in stock I have plenty of 3mm rose cut cabochons, and a certain number of 4mm rose cut cabochons. This material is sublime; eye clean with superb lustre and the faceting is perfect and precise. Hence the not so many of the 4mm. I think that this is bound to go fast, not wanting to sound like a used car salesman, but it’s not so easy to find clean and reasonably priced tanzanite in these cuts. And these are reasonable; the 3mm rose cuts are $5.50 per stone and the 4mm rose cuts $17.50 per stone, all in USD. Tanzanite is from Tanzania, which contributes to a rather fluctuating supply, and is a relative newcomer to the world of cut stones, not being discovered until the 1960s. It is routinely heat-treated, as unless it has undergone some natural heating at its point of origin (which is rather unusual) it is generally a brownish colour in its natural state, and these stones are indeed heated.
