Item Description

Thomsenolite is a rare hydrated sodium calcium aluminum Halide, and discrete, isolated Thomsenolite crystals are rare.

These Thomsenolites have the classic flat terminations, and they are associated with pearly Cryolite crystals up to 1.5 cm on massive cryolite matrix. There may be other minerals as well, present. For the last century and a half, Thomsenolite specimens from Greenland have been, and continue to be, the standard for the species. The locality is long gone and underwater.
