Fluorite occurrence, Mandrosonoro, Ambatofinandrahana, Amoron'i Mania, Madagascar
A cabinet sized specimen form a recent find of fluorite in Madagascar, certainly the best examples from the country found to date.
I first started seeing small amounts of this material in 2016, but it was not until last year that I saw well crystalized examples. These display a degree of UV reactivity-- not quite as strong as the stuff from Rogerly, but the phenomenon is definitely present.
At the moment these seem to be ridiculously undervalued-- you are getting a lot of bang for your buck. Even the abundant Chinese fluorites would be much more expensive, for a piece of comparative quality.
Most of what was available in Tucson (and even mores in Madagascar) was significantly damaged, these are some of the better examples I have come across.
