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.
Untreated morganite often has a strong orange color component, creating a salmon color.
Morganite crystals can be large, with specimens from Brazil weighing over 10 kilograms.
Morganite was named after J.P. Morgan, one of the greatest financiers in history.

Morganite can be pink, purplish pink, or orangy pink; often light in tone.
Although commonly light in tone, top-quality material is a strong pink.
Faceted morganite, in light and stronger colors, usually has no eye-visible inclusions.
Light-colored crystals might be cut a little deep to intensify the color.
