From Kat Florence’s heritage collection, this gem is one of the most important rainbow moonstones from Sri Lanka ever presented in jewelry. It is a true natural phenomenon, designed for those seeking an irreplaceable piece.

Fewer than five moonstones in the world exceed 10 carats with completely clean clarity. After decades of working with this material and reviewing over fifty metric tons, only four or five specimens of this level have been identified. This is one of those rare exceptions.

The gem, perfectly cut, weighs 12.12 carats. Its color play is extraordinary: intense blue flashes, yellow reflections, and an iridescent effect naturally combining blue moonstone and rainbow moonstone within a single crystalline structure with nearly impossible transparency.

Those familiar with this material know such clarity is never seen. Thousands of kilograms are processed each year into commercial cabochons, but finding a crystal of this purity and cutting it this way is exceptional.

For collectors of extreme-variety gems, few pieces can be considered as absolutely irreplaceable as this.
