Identikit. Transparent and crystalline: not by chance is called aquamarine that glitter even under lowlight conditions. A quality that makes it a “star” of fine jewelry. Like emerald, is a stone that belongs to the beryl family. The structure, however, is very different from the green gem: the iron impurities inside give that deep azure blue color, while chromium and vanadium tinged with green emerald. Almost always, the aquamarine is without inclusions: whether appear the star effect or the one called cat eyes it becomes invaluable. Its hardness allows jewelers to experiment with innovative cuts and, in fact, has been used for the Color du Temps necklace from the Peau d’âne collection by Van Cleef & Arpels, for the jewelry designed by Tiffany in the movie The Great Gatsby, for the Bulgari Serpente bought by Justin Bieber during the charity auction at Cannes Film Festival.

Provenance. The best known reserves of aquamarine are those in Minas Gerais, whose buds have a distinctive deep blue color. Always in Brazil there is the Santa Maria de Itabira mine with deep blue, stones which are a favorite choice of gemologists. Other deposits are exploited on an industrial scale in the Urals, Nigeria, Madagascar, Mozambique and Pakistan.
