Discovered in Madagascar in 1910. Named by George Frederick Kunz of Tiffany & Co.—the same man who gave his own name to kunzite gave this stone the name of J.P. Morgan.

A member of the beryl family, alongside aquamarine and emerald. Trace manganese produces the pink. The same beryl, but iron makes aquamarine, chromium makes emerald, and manganese makes morganite. One trace element different, and the stone receives an entirely different name and history.

Found in Brazil, Afghanistan, and Mozambique. Likely the only gemstone named after a turn-of-the-century financier.
