Aquamarine

L'aquamarine is a precious stone belonging to the beryl family, like emerald. Its characteristic light blue to blue-green colour is reminiscent of seawater, from which it takes its name. The term aquamarine comes from the Latin "aqua marinaliterally meaning "sea water. This stone is highly prized in the luxury jewellery sector, particularly in Thailand, where the company SMV Thailand uses it to create exceptional jewellery.

Origin and training

Aquamarine forms in igneous and metamorphic rocks. It is mainly extracted from mines in Brazil, the world's largest producer, but it is also found in Russia, Pakistan, Nigeria and Zambia. Aquamarine's blue colour is due to the presence of minute traces of iron in its crystalline structure. The higher the concentration of iron, the more intense the colour of the stone.

Physical and chemical properties

On the Mohs scale, which measures the hardness of minerals, aquamarine falls between 7.5 and 8, making it a relatively hard stone, suitable for everyday use in jewellery. Its chemical composition consists mainly of beryllium, aluminium, silicon and oxygen. It has excellent clarity and is often free of inclusions, making it even more precious.

The craftsmen of SMV Thailand use this stone to adorn rings, necklaces, bracelets and earrings. It is often cut in oval, round or emerald shapes to maximise its beauty and brilliance. Because of its clarity and colour, aquamarine is also used as a centre stone in engagement rings and bridal jewellery.
