Product Description

For sale is a  pseudomorph/alteration specimen of Glendonite from the from the type locality, Glendon, NSW. These specimens start out as Ikaite which is calcium carbonate (Calcite) but with a handful of water molecules attached to it. Once the Ikaite reaches a temperature above 8°C (46°F), it pseudomorphs into Calcite, which is what it is now, this process is not reversible.  These are pretty unique, very very few minerals actually form at such low temperatures, the only other  mineral that comes to mine is ice crystals. This bi-pyrimidal single crystal is of an excellent size for this old locality.  Ex Bernie Whyte collection. Please remember our prices are in Australian dollars.
