This is a single rosette composed of individual radiating crystals of cavansite. It exhibits an intense, royal blue, and is both lustrous and translucent. Aside from the very, very neat form of it, it is one of the finest cavansites for quality I have handled in 10 years; and simply one of the most gorgeous, of all. Competition quality miniature, this...NOT just another representative exampole you could beat with more money. I have literally seen thousands of these things, so believe me, I do not rave careflessly on this one.
