Pink Morganite from Brazil

 

Morganite is the rare pink-orange form of beryl, a mineral family that includes well-known gems such as emerald and aquamarine. Morganite is a good hard gem with a lovely pastel color that has become a popular jewelry stone.

Morganite was first discovered in Madagascar in 1910 and named in honor of J.P. Morgan (1837-1913), the American banker and philanthropist, by the New York Academy of Sciences. George F. Kunz, the famous gemologist who headed the geological section of the Academy, noted that Morgan was honored especially for his gift of several major gem collections to museums such as the American Museum of Natural History.

All the members of the beryl family are beryllium aluminum silicates by chemical composition. The different beryl colors are the result of trace elements. Emerald is colored green by chromium and vanadium, while aquamarine is colored blue by traces of iron. Golden or yellow beryl is also colored by traces of iron. Morganite derives its peach or pink color from manganese, though Morganite specimens typically contain traces of cesium and lithium as well.

Morganite, like other beryls, is quite a hard gem, with a Mohs rating of 7.5 to 8.0. Beryl has a refractive index of 1.577 to 1.583 and a density of 2.72. 

In general, Morganite tends to have much fewer inclusions than emerald, so eye clean specimens are common. Morganite colors range from a peach orange to salmon pink to a pure pink. The color is nearly always a soft pastel and saturated colors are quite rare.

A pure pink is the rarest and most valuable color in Morganite. We have just cut a number of beautiful pinks from some exceptional rough material from Brazil, in sizes ranging from 2.5 to 16 carats. These are mainly ovals and cushions, perfect for rings or pendants.

News from AJS and the Gems World

 

A Very Rare Pink 16 ct Malaia Garnet

We are pleased to announce the latest addition to our rare gem collection, a 16.55 ct Malaia Garnet from Madagascar, with a special report from GIA.

Malaia (or Malaya) Garnet is a rare hybrid of pyrope and spessartite garnets. It is typically found in a cinnamon color. Pink Malaia garnets with a pink-red color shift are very rare, and have mainly been found in Bekily in Madagascar.

The rare pink Malaia garnets usually occur only in small sizes (1 to 2 cts), so this exceptional 16.55 ct specimen is particularly rare. It has been certified by Gemological Institute of America (GIA) with a special Notable Letter documenting its extreme rarity.

Ask the Gem Experts

Each month we answer questions from our customers. We welcome your questions and you can submit a question from our contact page.

Are gem silica chrysocolla and chrysocolla the same gemstone? I find the names confusing, but I am looking for a chrysocolla that is hard enough for jewelry. DC, USA

The name are indeed confusing, and this is perhaps why the more valuable Gem Silica Chrysocolla is usually referred to as Gem Silica in the trade, to distinguish it from the more common forms of Chrysocolla.
 
Members of the Chrysocolla family range in colored from deep blue to blue-green, colored by traces of copper. They have a wide variation in Mohs hardness, ranging from 2 to 7, because of differences in chemical composition. Chrysocolla Chalcedony is a heavily silicified form of chrysocolla that forms in quartz deposits and can be very hard. This variety is known in the trade as Gem Silica, with particularly fine examples with excellent translucency coming from the Inspiration Mine in Arizona, USA.
