Most of the morganite on the market comes from pegmatite mines in Minas Gerais, Brazil. Afghanistan, Mozambique, Namibia, and the US have been minor and inconsistent sources. While it’s only a minor producer today, the original Madagascar deposit still sets the standard for the best material. The Madagascar location’s yield of magenta-colored rough was superior to crystals from other sources.
Strong color in morganite is rare, and gems usually have to be large to achieve the finest color. Although morganite is rarer than Aquamarine, large cut stones are readily available on today’s market. That’s probably because Morganite hasn’t been promoted to the jewelry-buying public nearly as widely as Aquamarine or Emerald.
Morganite was named to honor American financier and gem enthusiast J.P. Morgan. Following the discovery of a new locality for rose beryl in Madagascar in 1910, George Kunz proposed the name morganite at a meeting of the New York Academy of Sciences on 5 December 1910 to honor his friend and customer J.P. Morgan for his financial support for the arts and sciences, and his important gifts of gems to the American Museum of Natural History in New York and to the Museum of Natural History in Paris. Morgan was one of the most important gem collectors in the early 1900s – his collection was partly assembled by Tiffany and Company and their chief gemologist, Kunz. On October 7th, 1989, one of the largest specimens of Morganite was uncovered. It was found in the Bennet Quarry of Buckfield, Maine, and it was somewhat orangish in hue and about 23 cm long and 30 cm across. This well-formed crystal weighed in at just more than 50 pounds, and was called "The Rose of Maine".
COLOR - One of the interesting properties of morganite noted by Kunz was its intense red-colored fluorescence when exposed to X-rays, but no phosphorescence when the X-ray source was turned off. Although commonly light in tone, a top-quality material is a strong pink.
CUT - Light-colored crystals might be cut a little deep to intensify the color.
CLARITY - Faceted morganite, in light and stronger colors, usually has no eye-visible inclusions.
CARAT - Morganite comes in a variety of sizes, including large faceted gems and designer cuts.
MULTIPHASE INCLUSIONS- Morganite can contain liquid inclusions that contain gas bubbles and possibly also solid phases.
FLATTER PRISMS - Morganite forms beautiful hexagonal prism crystals that tend to be flatter than aquamarine crystals.
PASTEL - Morganite often comes in lighter, very delicate pastel shades of pink.
