The name Aquamarine refers to blue colour beryl variety, that due its colour to iron traces in place of chromium which emerald dues its colour to.
Aquamarines and sapphires are the most valuable blue gemstones. Rarely the aquamarine reaches an intense colour, generally it shows a more or less intense shade of turquoise.Aquamarine can be found in noticeable carat weight crystals and generally almost without inclusions, although a small inclusion is often a guarantee of its natural origin to the gemmologist, as synthetic aquamarines recently produced in Russia present beautiful clear crystals without inclusions.
The natural aquamarine on the other hand is not subjected to special treatments apart from heat treatment in order to eliminate the secondary green hue, which raw material often presents.
Most aquamarine mining takes place in Brazil where crystals of noticeable carat weight has been found.
The aquamarine is often confused with the blue topaz but its rarity is not comparable; an excellent aquamarine with a strong colour saturation is rarer in each carat weight.
The main mine of aquamarines is Santa Maria de Itabira, in Brazil, where the most precious examples, intense and deep light blue, come from. For this, the gems with this hue are called “Santa Maria” and are distinguished by the “Espírito Santo ” aquamarines, from Brazilian state Espírito Santo, with less deep and lighter – but extremely captivating- blue colour. Finally, another splendid hue was named after a beautiful Brazilian queen in 1954 and it is “Martha Rocha”.
