This is a small specimen, but most of it consists of a crystal of cryolite about 9 x 6 x 5 mm. Overall, the crystal appears to be more or less sharply formed and transparent but frosted and “bumpy” (macro photos). Under a scope, some faces appear to be composed of numerous smooth, but slightly stepped, segments (top of first close-up). Other faces (second close-up) seem very smooth (bright areas) but have numerous hillocks or “warts”. Most large cryolite crystals at MSH are encrusted by zeolites. However, to me, the “warts” on this specimen look like a second generation of cryolite rather than an encrusting zeolite. But I am not sure. The crystal fluoresces pale blue-white – typical of “naked” cryolte at MSH. It sits on a bit of microcline with small sections of petersenite-(Ce) prisms replaced by synchysite-(Ce) (second macro photo). The specimen is from the Poudrette pegmatite, August 1997. (Peatite-(Y) and ramikite-(Y) were found a few days later.)
