Glassy and lustrous, colorless, chabazite variety phacolite crystals RICHLY cover both sides of this excellent and very showy crust from the Flinders area of Victoria, Australia. Chabazite is common, but phacolite is UNCOMMON from the Flinders area and this a good one. Phacolite is a lens-shaped variety of chabazite, due to twinning/multiple twinning of the rhombohedrons. Ex. George Elling Collection.
