The Regal

Pollucite is a caesium-rich member of the zeolite group, formed in the late pockets of lithium–caesium–tantalum pegmatites. It is common enough as a massive, cloudy material and exceptionally rare as a clean, transparent crystal large enough to facet.

The Regal is a near-colourless cushion of 39.71 ct, cut in a combined brilliant and step pattern, and documented in an independent laboratory report as natural pollucite with no detected treatments.
