Morganite: A Romantic and Elegant Pink Gemstone

Morganite is a beautiful pink to peach colored gemstone that has seen quite a significant rise in popularity, especially since 2010. As a variety of beryl, morganite the same mineral family as emerald and aquamarine but is distinguished by its soft and romantic hues. Morganite’s high durability, lovely color, and increasing use in engagement rings has made it one of the most sought-after gemstones.

It’s often found in association with other beryl varieties like aquamarine and emerald, as well as minerals such as tourmaline and quartz. Morganite can form large, well-defined crystals, making it a favorite among collectors.

Physical Characteristics

Morganite’s known for its pale pink to peach color, which can range from soft pastel tones to more vivid hues, depending on the concentration of manganese. The stone’s transparency, durability, and luster make it ideal for various types of jewelry. Morganite’s beauty can be enhanced through heat treatment to deepen its pink color, although naturally colored stones are especially valued.

Morganite’s Color and Pleochroism

Morganite’s color ranges from slightly yellowish-orange to pink, and its hues pair beautifully with rose gold settings, further enhancing its romantic appeal. Its color is pleochroic, which means that the stone can show slightly different colors depending on the angle from which it is viewed. By orienting the crystal in a specific direction, gem cutters are able to maximize the intensity of morganite’s pink color.

But where does the pink coloration come from? Trace amounts of manganese are responsible for its natural color, but it’s often times treated with heat or irradiation to increase its color saturation. These treatments are common, undetectable, and widely accepted in the market, though it’s important that sellers always disclose treatments to buyers who prefer untreated gemstones.

Durability of Morganite

As a member of the beryl family, morganite has a Mohs hardness of 7.5 to 8, making it highly durable and suitable for everyday wear in jewelry. This hardness is comparable to sapphire and topaz, making it resistant to scratches from most common objects. Unlike emerald, morganite is relatively free of inclusions and fractures, which enhances its durability and overall value.

The market features three types of morganite:

Natural Morganite: Formed through natural geological processes, this is the most valuable and highly sought-after variety.

Synthetic Morganite: Lab-grown morganite shares the same chemical composition and physical properties as natural morganite, but it can be produced in unlimited quantities.

Imitation Morganite: Made from man-made materials like Nanosital or glass, these stones only mimic the appearance of morganite and are much less valuable.

As a collector, you should be aware of the differences and ensure you’re buying genuine natural or synthetic morganite rather than imitation materials, especially for high-value pieces.

Notable Specimens and Localities

Morganite was first discovered in Madagascar in 1910, and the gem was named after the financier J.P. Morgan by George Kunz, a gemologist for Tiffany & Co. Today, the finest quality morganite is mined in Brazil, particularly in Minas Gerais, which remains one of the primary sources of the gemstone. Other significant deposits can be found in Afghanistan, Mozambique, Namibia, and some parts of the United States (California and Maine).
