Morganite is the pretty, peachy-pink variety of beryl, cousin to more familiar beryls like emerald and aquamarine. Morganite's beautiful, ladylike colors are a result of the presence of manganese or cesium. Morganite was first discovered in California in the early 20th century and soon thereafter in Madagascar. It was named after J. Pierpont Morgan, an American banker and collector, in honor of his gemological and mineral contributions to the American Museum of Natural History in New York.
Though there are also small deposits in Brazil, Mozambique, Namibia, Afghanistan, and Russia, quality morganite remains relatively rare.
Like almost any gemstone, morganite is valued first and primarily on the intensity and saturation of its color, followed by size and clarity. It's also important to understand that morganite is pastel or pale in color by nature, so strong, intense hues are rare for this stone
