Morganite commonly occurs as an accessory mineral in granites, and is usually found in cavities and in granite pegmatites. Because of its hardness, it is sometimes found in alluvial
deposits. Morganite is found in association with quartz
mica, as well as other pegmatite
accessory minerals. The very first morganite to be described was a pale rose-colored specimen from California, where it was found with tourmaline
. Some of the finest morganite in the world comes from Madagascar. Rare forms of morganite come from Minas Gerais, Southeast Brazil
, where pure pink crystals are found, as well as some of the highly prized varieties containing aquamarine
and morganite in the same crystal. Other occurrences of morganite are found in Elba, Italy
; Mozambique, Namibia, Zimbabwe; Nuristan, Afghanistan; and in the United States, in the Pala District in San Diego County, southern California. Morganite is also found in Pakistan, where it was recently discovered for the first time.
