Introduction to Aquamarine

Aquamarine has a beautiful lustre and it is almost as popular as the precious gemstones ruby, sapphire and emerald. It is in fact related to the emerald, since both belong to the beryl family of minerals. The term aquamarine comes from Latin vocabulary, meaning ‘water’ and ‘from the sea’.

This entrancing gem displays a stunning range of colours ranging from a delicate light blue to a rich blue and blue-green, with the deep saturated blue being the most valuable variety.

The deeper blue hue occurs when the stone is heated to 750 degrees, and when observed under a microscope, it often shows shades of green.

Aquamarine forms into gorgeous, transparent crystals which are usually flawless, unlike the emerald which is generally flawed with inclusions (inherent fine cracks).

Main Source of Aquamarine

The main producer of aquamarine is Brazil, which has many mines across the country. Other prime sources are Australia, Myanmar (Burma), India, China, Kenya, Madagascar, Mozambique, Namibia, Nigeria, Zambia, Zimbabwe and the US.

The largest aquamarine gem was discovered in 1910 in the ‘Minas Gerais’ in Brazil – it weighed 110.5 Kg and was cut into numerous smaller gems with a total weight of more than 100,000 carats.
