EPT27AN6: A novelty from the summer of 2021: Very sharp crystals of Imayoshiite, a rare carbonate-borate of calcium and aluminum, many of them doubly terminated, with a prismatic hexagonal habit and very marked parallel growths, transparent, very lustrous and largely covered by white spheroidal growths of Shinichengite (this new mineral species was initially labeled as possible Tobermorite-Clinotobermorite). On matrix, associated with small reddish brown crystals of Datolite (variety bakerite) and Fluorapophyllite-(K). Very good quality for the species.
The species have been analyzed and we will send a copy of the analysis to the buyer.
