About Morganiteextended article

Morganite is the pink-to-peach gem variety of beryl, coloured by traces of manganese. It was named in 1911 after the financier and gem collector J. P. Morgan. Its soft, romantic pink has made it a popular modern jewellery stone, often shown in large, clean crystals.

Properties

Like all beryl it is hexagonal, hard (7.5–8) and forms prismatic to tabular crystals. Morganite is usually remarkably clean, and some material is gently heated to remove yellowish tints and emphasise the pink.

Occurrence

It forms in granitic pegmatites alongside other gem beryls. Brazil, Madagascar, Afghanistan, Pakistan and California (the Pala district) are notable sources. Related beryls include aquamarine, heliodor and colourless goshenite.

About Morganite

Morganite is classified as a cyclosilicate mineral in the beryl group and has the chemical formula Be3Al2Si6O18. It crystallizes in the hexagonal system and is one of the most visually varied minerals in the collector market.

Identification & care

Crystals commonly develop as prismatic hexagonal, often tabular; crystals may be large. Its color range is broad, including pink, rose, peach, salmon, and violet-pink. The luster is vitreous, the streak is white, and specimens range from transparent to translucent. The cleavage is imperfect basal. The fracture is conchoidal, which aids identification.
