A very interesting pseudomorph of Calcite replacing a starburst-like cluster of crystals of the rare the Calcium Carbonate mineral Ikaite. This very aesthetic specimen is the only one that I've seen of it's kind.
specimen size = 3 x 2.7 x 2 cm.

Calcite (Var: Glendonite) : CaCO3

Olenitsa River, White Sea Coast, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia

10.1 x 7.1 x 5.5 cm. These specimens have confused collectors since they first came out in the early 1990s as calcite after something embedded in concretions, then glendonite after ikaite, then as calcite after ikaite; and now classified as calcite variety thinolite, which is a pseudomorph after an unknown mineral. This is a strange, ...

Calcite (Var: Glendonite) : CaCO3

Olenitsa River, White Sea Coast, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia

A strange, biomorphic-looking pseudomorph of calcite var. thinolite, from Russia. The sharp orange-brown pseudomorphed crystals look like a crown or head of hair atop a pear-shaped object. This is a dramatic example of this sort of specimen, with a really wonderful overall form. 7.8 x 4.7 x 4.6 cm

Ikaite : CaCO3·6H2O

Olenitsa River, White Sea Coast, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia

Dimensions: 2.85 x 4.76 x 1.90 cm

This Ikaite specimen has been living in my freezer (along with two companions) since its purchase several years ago. At the time of purchase the crystals were frozen. They were kept packed in ice in a thermal cooler to prevent them from defrosting. I examined them while they were inside the thermal cooler prior ...
