PEZZOTTAITE PRINCESS CUT
3.9 millimeters
0.385 carats

Here is a faceted pezzottaite from Madagascar.  Pezzottaite was discovered in 2002.  It was initially believed to be a new deposit of red beryl, but after further study, the mineral was found to replace the beryllium in its crystal structure with cesium approximately 50% of the time.  This alters the molecular form, and removes the mineral from the beryl family (although it is still a member of the beryl group).  Many of this gemstone's properties are similar to beryl, with the same hardness and refractive index.

This gemstone is from the original pegmatite where the variety was discovered:  the Sakavalana Mine, Ambatovita, Mandrosonoro Commune, Ambato-Finandrahana District, Fianarantsoa Province of Madagascar.
