Aquamarine is often heated to intensify the colour and remove green tones, resulting in the strong blue coloured stones most often seen in jewellery.
The colour is caused by tiny amounts of iron present in the crystals and large clean stones are not uncommon. Legend has it that Aquamarine (which means seawater in Latin) was the treasure of Mermaids and that might just be right! On land it can be found in countries such as Mozambique, Madagascar and Zambia.
Description: Aquamarine is the blue-green variety of the Beryl family and is found naturally in a range of shades varying from pale bluish-green through to a strong sky blue. It can be found in Brazil amongst other places.
