Morganite
Morganite used to be called pink beryl. It belongs to the beryl group like aquamarine and emerald. The gemstone was discovered in 1910 in Madagascar. It is named after the New York banker and gemstone collector John Pierpont Morgan.
Morganites come in different varieties of pink, from very light, champagne or light purple stones to peachy and more vibrant pink. Morganite is 7.5 to 8 on the Mohs scale. The color is produced by the manganese it contains. Glassy luster and transparent to translucent transparency are typical for morganite.
Many of the stones found are dichroic, i.e. the color shading changes depending on the viewing angle. Intense colors are rarer and therefore more sought after. The most valuable ones are stones in intense pink. The price level is currently below that of other beryls, but there is great potential for increase. Morganite is of magmatic origin. One of the biggest found morganites is "The Rose of Maine" from the USA, weighing 13 kg. But morganites with more than 20 kg have also been found in Brazil. Morganites of the highest quality are currently found in Madagascar, Mozambique and Nigeria. Other important sites are located in Afghanistan, Brazil, Burma, China, Russia and the USA. Morganites are oft burned at temperatures of 400 degrees Celsius and more to improve the color, because burning makes the pink color more intense and yellow or orange color nuances disappear. This treatment is common for many stones on the market.
