Displaying gorgeous deep
raspberry pinks, Pezzottaite is a relatively new gemstone that has been
subject to much confusion due to its similarities with the Red variety of
Beryl, Bixbite.

Pezzottaite was discovered in November 2002 at the Sakavalana mine located
about 140 kilometers southwest of Antsirabe in southern Madagascar. The
initial deposit yielded some extremely rare large crystals and it is now
practically depleted although small amounts are now mined elsewhere in
Madagascar. The Sakavalana pegmatite where Pezzottaite was discovered was
mined by the French for Tourmaline during the 1940’s. The initial
Pezzottaite deposit was discovered in a large crystal bearing cavity that
also contained Tourmaline and Spodumene. Not surprisingly, Pezzottaite was
initially mistakenly sold as Tourmaline in Madagascar.
Pezzottaite is mined from granitic pegmatite’s using hand tools, making
its extraction slow and difficult.
Having a slightly different chemical composition to Bixbite (Be3Al2Si6O18)
it was named Pezzottaite (Cs[Be2Li]Al2Si6O18) in September 2003 after Dr.
Federico Pezzotta of the Museo Civico di Storia Naturale, Milan, Italy, in
recognition of his contributions to the mineralogy of Madagascar.
Pezzottaite has a variety of trade names including Madagascan Raspberyl,
Raspberyl and Raspberry Beryl. While Pezzottaite is closely related to the
Beryl family and is visually similar, it is in fact a unique species,
making its trade names somewhat of a misnomer.
Like Emeralds, inclusions in Pezzottaite are common, especially in the
larger carat weights. However, their rarity and novelty for gemstone
collectors has always been the primary factor. Pezzottaite has all the
attributes a gem needs - beauty, durability and rarity. Scarcer than Ruby,
these rare gems truly are a unique fashion statement.
