Twinned Phosphophyllite xl (Bancroft Coll.)

Item Description

This gorgeous thumbnail exhibits the incredible gemminess and unique blue-green color that makes phosphophyllite one of the most desired species in the mineral world. This phospho displays classic fish-tail twinning, high luster and transparency. This is a complete all-around crystal, truly classic in form. The couple of sulfide blebs on the back side add character, but this does not, in any way, affect the beauty and rarity of this specimen. Such crystals are today almost unobtainable in any size. Ex Pete Bancroft Collection and the specimen dates to the 1950s or 60s. Valued $1000
