Morganite
Overview
Morganites belong to the colourful group of beryls, which includes emeralds and aquamarines.
When the structure of a clear beryl is in a position to intercalate foreign elements such as iron, manganese, chrome or vanadium, the stone begins to take on different colours. If manganese is intercalated in beryl, the colourless gemstone turns into an alluring morganite.
In 1911 in New York, gemmologist G. F. Kunz suggested the stone to be re-categorised and renamed. The pink variety of beryl was ennobled to the status of a gemstone of its own. In honour of the banker and mineral collector John Pierpont Morgan, it was given the name under which it is known today – morganite.
Today the gemstone mainly comes from deposits in Brazil, Madagascar, Afghanistan and California.
