As a gemstone, Aquamarine has always interested me. There is something soothing about its clear connection with all things sea, ocean and still, clear water. It has a gorgeous blue colour, and it amazes me that planet earth can produce stones of these colours. The stone in my collection is a rough stone, not cut or polished with opaque cyan colouring. It has no other colours running through it, and the crystals reflect the light in a mesmirising manner. It is about 2 cm tall by 3 cm long.


The name for this gemstone is derived from the latin word, ‘aquamarina’ for being of the sea.

Aquamarine is a blue, or cyan form of the gemstone Beryl. These stones are generally a light blue, and deeper blue versions are called Maxixe. The iron ions within the stone give the fresh light blue colour. The relative combination of different iron ions controls whether the stone is classified as Aquamarine, Maxixe, Heliodor or Yellow Beryl. The colour does fade in sunlight. In terms of clarity, stones that are clear rather than opaque and are free of visible inclusions are more valuable. Aquamarine is relatively easy to mine so these stones are widely available meaning that you are able to shop around for what you want. A lot of rough gemstones are more opaque and look similar to a lot of waxy calcites.

The stones are predominantly comprised of Beryl, but also contain Aluminium, Silica and Iron.

Common places where this gemstone is found is Sri Lanka, Madagascar, Kenya and America.


The gorgeous cyan colour of Aquamarine and its ease of accessibility make a lot of these stones inexpensive and favoured for jewellery. There are a lot of pieces that do sell for a lot more money, with this being a semi-precious stone. It has a good grading system, and value is based of depth of colour as well as clarity. Most jewellers will sell inexpensive and expensive pieces.


Aquamarine is the stone of ‘courage’, can provide emotional and intellectual stability and creates balance and order. It may pay to keep this stone somewhere that you feel is dominated by disorder. For me this would be our pantry, although having Aquamarine sitting on one of the pantry shelves may seem a bit out of place.
