ROCK TRIVIA: AQUAMARINE
Aquamarine is part of the Beryl family. This group of minerals includes the green Emerald, the pink Morganite and the yellow Heliodore.
The largest find of gemstone quality aquamarine was in 1910 when the"Minas Gerais" mine in Marambaya, Brazil, unearthed a stone of 243 pounds. It was cut into gemstones that had a total weight of more than 100,000 carats.
In the late 1980s, an exceptionally large Aquamarine crystal was found by three Brazilian miners. They accidentally dropped the Aquamarine, breaking it into three pieces. The finest and largest piece - which measured about 2 feet long and weighed 60 pounds-was saved and named 'Dom Pedro'. It was cut in Idar-Oberstein, Germany in 1992 by the gemstone designer Bernd Munsteiner and is the largest single piece of aquamarine to have ever been cut.
The 2 pictures below are the cut and uncut stone. Brazil was approximately two feet in length and weighed almost 60 pounds. The picture of the uncut stone was taken by Munsteiner. The picture on the left is from the Smithsonian where the gem now resides.
