Named after J.P. Morgan, one of the greatest financiers in history, Morganite is the pink to orange-pink variety of beryl, a mineral that includes emerald and aquamarine.
Morganite's subtle color is caused by traces of manganese. Because morganite has distinct pleochroism—pale pink and a deeper bluish pink—it’s necessary to orient the rough carefully for fashioning. Strong color in morganite is rare, and gems usually have to be large to achieve the finest color.
Most of the morganite on the market comes from pegmatite mines in Minas Gerais, Brazil. Afghanistan, Mozambique, Namibia, and the US have been minor and inconsistent sources. While it's only a minor producer today, the original Madagascar deposit still sets the standard for the best material. That location's yield of magenta-colored rough was superior to crystals from other sources.
