Inyoite is a RARE borate. This is an EXCELLENT and showy two-sided CABINET specimen featuring a multitude of sharp, very glassy and zoned, pseudorhombic crystals to 6.3 cm! The sharp, two-sided crystals at each end are standouts. This showy piece comes from a recent, but small find in arid, high altitude valleys of Argentina and is the finest specimen we have offered to date in the auctions from the lot. There is minor contacting, on this essentially pristine specimen. All of the major crystals are undamaged.
