Discoveries: Pezottaite is a newly discovered member of the beryl group
found in Madagascar.
Londonite is also a new discovery.
Pezzottaite made its commercial debut at the 2003 Tucson Gem Shows, where it was marketed as "Raspberyl" or "Hot Pink Beryl". Subsequent research found that, while similar to beryl, the gem material is actually a new mineral. It was named 'Pezzottaite' in honor of Dr. Federico Pezzotta of the Natural History Museum in Milan, Italy, who has done significant research on the mineralogy of Madagascar.
Earlier Londonite was approved as a new mineral species in 1999. This rare aluminumberyllium borate is the cesium-rich analogue of rhodizite. The only known source of gemquality londonite is the Antsongombato pegmatite in central Madagascar, from which some rhodizite-Iondonite have been faceted. The gemstones are colorless to greenish yellow. Some near-colorless rhodizite-Iondonite from Antsongombato has been irradiated to greenish yellow or yellow using X-rays, according to G./A
