Morganite is the pink variety of beryl. When mined it first appears as a peach color, but when exposed to light turns to pink which is usually a fast color. The stone gave help against foes in battle or in litigation; the wearer was rendered unconquerable. Its crystals are tabular in form displaying primarily flat lustrous basal faces, and etched faces of the first-order prism, and prominent leveling by faces of the second-order pyramid. Morganite crystals of great beauty have been found in Madagascar, Afghanistan, and Brazil, but crystals from the White Queen mine, discovered by Fred Sickler in 1901 and later worked by Norman Dawson, are among the most remarkable found anywhere. Morganites from the Queen mine associate with fine druses of cleavelandite crystals and quartz crystals.
