Aquamarine Facts

Colour: Aquamarine comes in many hues of blue ranging from a soft pale sky blue to a vivid turquoise like the deep oceans. Aquamarine is a type of beryl (emerald is the deep green variety of the mineral).

Appearance: More frequently aquamarine is transparent, however it can also be opaque. It grows in a hexagonal crystal formation, typical inclusions are fine hollow rods that sometimes reflect white light. When growth lines are present in larger numbers a cat's eye effect or even a six rayed star is possible.

Rarity: Aquamarine is a well-sourced gemstone, however certain colours and desired inclusions are rare. Madagascan aquamarine tends to be of a deeper blue shade which is one of the most sought after colours of the gem at the present time. Cats eye aquamarine is also very popular which is usually cut into cabochon stones to maximise the optical effect over the surface of the stone.

Mohs Scale Hardness: Aquamarine measures 7.5 on the Mohs scale so is one of the harder grades of gemstone.

Sourced: Aquamarine is most commonly found in Brazil however it can also be found in Mexico, United States, Brazil, Russia, Afghanistan, India, Nigeria and Madagascar. 

Formation & History Of Aquamarine

The popularity of colours in this beautiful stone has changed over the past few centuries, in the 19th Century the most sought after shade was the sea green / blue, whereas in more recent times the sky blue and dark blue varieties have become more popular. It's green / blue colouring is given by the amount of iron content the gem contains.

With most of the aquamarine that is available, a heat treatment is often applied to enhance its blue hues and the untreated stones tend to have a more greenish tinge to them. The blue hues can also be lost by overheating the stones - we recommend that it is always best to set your gemstone last so that it does not come under any unnecessary heat.

Aquamarine being the colour of water has been named 'The Sailors Lucky Stone' due to its link to the life-giving force of nature. In Latin tradition it has also been named 'Water of The Sea'.

Old traditions say that by wearing aquamarine you will enjoy a happy marriage and it is said to bring the woman who wears it joy and wealth!

Jewellery Design

Aquamarine is really growing in popularity with the recent trends in semi-precious gemstone jewellery, popular combined with silver and other pastel coloured gemstones.

Aquamarine is a strong stone so it is suitable for various jewellery designs and settings, however its colour is heat sensitive so care needs to be taken when soldering (as we have said previously - always set last). Being based in Cornwall and working 5 minutes from the coast means we can't help but have a strong connection with the sea here at Kernowcraft, which is why aquamarine really is one of our favourite gemstones.

This gemstone looks especially great with silver, as well as other pastel coloured gemstones.
