The mineral Vlasovite is inherently quite rare, being discovered in Russia in 1961 - the single occurrence of gem grade examples is at Sheffield Lake in Quebec. The Vlasovite forms in concert with the much more common Eudialyte and, since the initial find here, very few stones have been cut. A Gems & Gemology article from as recently as 2012 mentions the largest faceted example as 0.52 ct. and we personally have had gems to just over one carat. So, a nice way to try for a larger example? A massive Vlasovite cab - surely among the largest ever cut. A great conversation piece with fine color and a great polish.
