Iceflake

Pollucite is a caesium-rich zeolite that crystallises in the last pockets of lithium–caesium–tantalum pegmatites. Massive, cloudy material is not unusual; transparent crystals clean enough and large enough to facet are among the harder rarities to source.

Iceflake is a near-colourless octagon of 46.32 ct, cut in a step and modified brilliant pattern, and documented in an independent laboratory report as natural pollucite with no detected treatments.
