A significant specimen from a major french find of some years back, generally considered to have produced the finest specimens of the species (I am told). Both species here are extremely rare in any display-quality specimens, and this is the first I have had of either one. This large plate features a very large deposit of umohoite in rich concentration on the top of the specimen. Hundreds of crystal clusters of Calcurmolite surround it. From the prominent radioactives collection of Alain Caubel, of France.
