A novelty for the summer of 2021 and, in all likelihood, the best known for the species so far. Imayoshiite occurs in numerous very sharp crystals, with a tabular habit and hexagonal contour, transparent, very lustrous and between colorless and slightly yellow, occuring together with spheroidal growths of pinkish Bultfonteinite and with small white fibrous coatings of some Tobermorite group species, on Andradite matrix. These specimens have been analyzed and we will send a copy of the analysis to the buyer.
