Morganite is named after the American banker and collector J.P Morgan.

Morganite, also known as "pink beryl", "rose beryl", "pink emerald", and "cesian (or caesian) beryl", is a rare light pink to rose-coloured gem-quality variety of beryl. Orange/yellow varieties of morganite can also be found, and colour banding is common.

The pink colour of Morganite is unstable and fades when heated to 500°C. The colour can be restored by radioactive bombardment.
