Glendonite

This is a very unique specimen: A spherical cluster of 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 - subsequently the name stuck. (I much prefer to say “Glendonite” than “Calcite pseudomorph after Ikaite” - nobody’s got time for that). A great, unique specimen in excellent condition. Location: Olenitsa River, White Sea Coast, Kola Peninsula, Murmanskaja Oblast, Russia Size: 3.5 x 2.5 x 2.8 cm
