What is Morganite?
Morganite is the pink to peach gem variety of beryl, prized for delicate colour, clean transparency and the elegant hexagonal crystals of its pegmatite host.
Mineralogy and crystal structure
Reference formula: Be3Al2Si6O18. Morganite is a manganese-coloured gem variety of the beryl mineral. Morganite is not a separate mineral species from beryl. Its ideal host formula is Be3Al2Si6O18, while pink and peach colour is commonly associated with manganese and may be modified by other trace elements. The structure shown is a labelled beryl representative model, not a claim that colour creates a new lattice. The reference record uses hexagonal symmetry. Typical hardness is 7.5–8 on the Mohs scale and specific gravity is approximately 2.6–2.9.
Colour, lustre and habit
Typical colours include pink, peach, rose, lilac. The usual prismatic, tabular, massive habit and vitreous, pearly lustre help describe a specimen, but colour alone is not diagnostic.
Formation and notable localities
Morganite forms in or is associated with beryllium-rich granitic pegmatites and late hydrothermal pockets in evolved igneous systems. Important documented localities include Brazil, Madagascar, Mozambique, Afghanistan, Pakistan, the United States and Namibia.
Soft colour in a true beryl crystal
Morganite combines a calm pink palette with the structural credibility of beryl. A well-cut stone or sharp pegmatite crystal is most compelling when colour, clarity, treatment history and locality are stated together, allowing the buyer to judge the specimen rather than an exaggerated colour label.
Collecting and care
Morganite is fairly hard but can chip along fractures and edges. Avoid sudden thermal shock, harsh chemicals and ultrasonic cleaning when inclusions or treatments are present; disclose irradiation, heating or other treatment before sale.
