AQUAMARINE - THE MARCH STONE

Aquamarine is one of our most popular and best-known gemstones, and distinguishes itself by many good qualities. It is almost as popular as the classics: ruby, sapphire and emerald. In fact it is related to the emerald, both belonging to the beryl family. The colour of aquamarine, however, is usually more even than that of the emerald. Much more often than its famous green cousin, aquamarine is almost entirely free of inclusions. Aquamarine has good hardness (7.5 to 8 on the Mohs scale) and a wonderful shine. That hardness makes it very tough and protects it to a large extent from scratches. Iron is the substance which gives aquamarine its colour, a colour which ranges from an almost indiscernible pale blue to a strong sea-blue. The more intense the colour of an aquamarine, the more value is put on it. Some aquamarines have a light, greenish shimmer; that too is a typical feature. However, it is a pure, clear blue that continues to epitomise the aquamarine, because it brings out so well the immaculate transparency and magnificent shine of this gemstone.
 
'Santa Maria' sets pulses racing
The bright blue of this noble beryl is making more and more friends. The various colour nuances of aquamarine have melodious names: the rare, intense blue aquamarines from the Santa Maria de Itabira mine in Brazil, which make every gemstone lover's heart beat faster, are called 'Santa Maria'. Similar nuances come from a few gemstone mines in Africa, particularly Mozambique. To help distinguish them from the Brazilian ones, these aquamarines have been given the name 'Santa Maria Africana'. The 'Espirito Santo' colour of aquamarines from the Brazilian state of that name is of a blue that is not quite so intense. Yet other qualities are embodied in the stones from Fortaleza and Marambaia. One beautiful aquamarine colour was named after the Brazilian beauty queen of 1954, and has the name 'Martha Rocha'.
It can be seen from the names of aquamarine colours just how important Brazil is among the countries where aquamarine is found. Most of the raw crystals for the world market come from the gemstone mines of that large South American country. Every now and then, large aquamarine crystals of immaculate transparency are also found with a magnificent colour, a combination which is very unusual in gemstones. And very occasionally, sensationally large aquamarine crystals come to light in Brazil, such as the crystal of 110.5 Kg found in 1910 in Marambaia/Minas Gerais, or for example the 'Dom Pedro', weighing 26 Kg and cut in Idar-Oberstein in 1992 by the gemstone designer Bernd Munsteiner, the largest aquamarine ever to have been cut. However, aquamarines are also found in other countries, for example Nigeria, Zambia, Madagascar, Mozambique, Afghanistan and Pakistan.
