Item Description

A large mass of sold white Cryolite associated with greenish-brown rhombs of Siderite and minor Galena(?) from the famous locality in Greenland, which is the type locality for Cryolite. The Cryolite shows minor semi-crystalline faces, but it's mostly massive. The Siderite crystals measure up to 1.5 cm, but they all seem to be cleaved, so this is mostly a reference specimen. From the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered. The piece comes with a 3x5 card label that states it was part of the Manley Collection in Duke University in North Carolina.
