 Glendonite
Glendonite's the common name for calcite after ikaite - most specimens come from the Olenitsa River, White Sea Coast, Karelia Republic, Kola Peninsula, Russia. Ikaite is calcium carbonate hexahydrate and it's only stable at near-freezing temperatures (as in year-round arctic rivers such as the Olenitsa). The color is due to mud inclusions as the calcite replaced the ikaite. The larger image (right) shows a 2-inch diameter glendonite from Ile Ellesmere, Nunavut Canada. Note the lighter color and less open morphology. Thanks to Don Smoley's Minerals & Gems' table at the 2001 Carnegie Gem & Mineral Show for the specimen!
