Pezzottaite
Pezzottaite was named after Dr Federico Pezzotta for his work on the granitic pegmatites of that island. Pezzottaite was discovered at the Sakavalana Mine, Ambatovita, Madagascar in 2002.
Pezzottaite has very rich, intense, distinctive pink colour.
Pezzottaite is one of the most rare and beautiful gems on the market nowadays.
