In 1910, pink beryl was first discovered on a small island in Madagascar. In December 1910, the New York Academy of Sciences named the ore of this species under the name of the financial industry JPMorgan. Morgan was one of the most important jewel collectors of the early 20th century, and the collection was partly collected by Tiffany and its chief gemmologist Kunz.

What is Morgan Stone?
Morgan Stone, a beryl with a soft pink or orange-pink color, is often lighter in color, so it is also known as "fan beryl", "rose beryl" and "pink emerald".
When you mention the name Morgan Stone, you will immediately think of beautiful pink, purple pink and orange pink.
Morganite is mainly produced in the pegmatite mines in the Minas Gerais region of Brazil, so larger crystals can often be seen. In addition, there are small outputs in Afghanistan, Mozambique, Namibia and the United States. Although Madagascar has a small output, it is rich in color and high in quality.
The color of the Morgan stone is mainly light pink, orange pink, pink and purple pink. Currently, the pink morgan stone is more favored on the market, and its pink color is caused by divalent Mn ions.
The purity of the Morgan stone is high, and no obvious inclusions are visible in the faceted gemstone. In addition, due to the lighter color, special cutting methods are often used in the cutting process to enhance the color and fire color.
Optimization of Morgan Stone
Morgan stone can be optimized, and the common methods are heat treatment and irradiation.
Heat treatment is a common optimization method for morganite. It requires only a relatively low temperature heat treatment to remove the yellow or orange tone of the morganite stone, giving the morganite a pure pink hue. The color obtained by heat treatment is stable and does not fade.
The heat treatment method is to amplify the change of the heat content of the inclusions, but due to the high purity of the Morgan stone, it is usually impossible to accurately detect.
Radiation-treated morganite is rare in the market, and the source of irradiation is gamma rays or neutron rays, which can obtain orange-rich morganite. Because this color of the Morgan Stone is not highly accepted in the market, and the half-life of the irradiation is more than two years, there are not many on the market.

Maintenance of Morgan Stone
Morgan stone is a kind of gemstone with good durability and generally does not require special maintenance. For a long time, the Morgan stone is stable in color and does not fade.
It should be noted that try not to place the Morgan stone in a higher temperature environment and the color may change.
Ultrasonic cleaning agents can be used for the cleaning of Morgan Stone, but when there is more content, it can be washed with hot soapy water.
