This is a very unique specimen: A spherical cluster of dark-brown Calcite crystals pseudomorphed after Ikaite. The Calcite chemically replaced the mineral Ikaite while retaining the crystal shape of the original Ikaite. Although not an official name, this particular specimen/pseudomorph is referred to as Glendonite because of its initial discovery in Glendon, Australia, and subsequent findings such as in Russia then retained this descriptive name. A rare and unusual find in excellent condition.
