17.8 x 10.6 x 4.8 cmAn excellent large cabinet specimen of sharp, translucent halite crystals from Poland that have this amazingly pretty green color from inclusions of malachite the halites picked up as they grew. You would swear this is a specimen of green fluorite from some new locality, unless you were to lick it and realize that it is salt (but do not lick it - natural halite specimens can harbor bacteria). The largest crystal is 4.1 cm and the base of this huge specimen is a banded crust of halite.
