Morganite
Be3Al2(Si6O18)
Morganite is pink to peach beryl coloured by manganese, from Minas Gerais (Brazil), Pala and Mesa Grande (California), Madagascar and Afghanistan; it forms tabular rather than prismatic crystals. Named for J. P. Morgan in 1911, it is sold as etched gem crystals and cut stones. Most peach morganite is heated to pink.
