The majority of the pink beryls available in the trade have undergone some sort of heat treatment or irradiation to improve their colour and to remove less desired yellowish and orangish hues. Those treatments are often not detectable by gemmological laboratories, especially the low temperature heat treatment.
The first morganites were discovered in 1910 in Madagascar. The mesmerizing pink beryl was later named morganite by famous gemmologist George Frederick Kunz in honour of the well-known financier and gemstone enthusiast J.P. Morgan.
Morganites are from sources in Afghanistan, Pakistan, Russia, the United States, Madagascar, Mozambique, Namibia, Zimbabwe and China but Morganites from Brazil are particularly known for good quality and colour.
