Aquamarine beads are especially popular due to their aquatic blue colours. The name "Aquamarine" is Latin for "water of the sea" and was regarded as a lucky stone for sailors. The deep blue Aquamarine is the considerably more in demand than the other shades of blue.
Aquamarine ranges from green to deep sky blue. Whatever the colour may be, it is always even throughout the whole stone. This evenness of colour is caused by a small bit of iron that is trapped inside the gemstone. Sometimes, Aquamarine that is found to be less attractive in colour is heated to about 400 degrees Celsius until the desired Aquamarine blue is obtained. A special feature of Aquamarine is the "dichroism". This means that, depending on the angle at which the stone is viewed, the colour is either blue or colourless.
Characteristics of Aquamarine beads
Like Emerald, Aquamarine belongs to the Beryl group. Despite the fact that Aquamarine has a hardness of 7.5 to 8 on the Mohs scale, it is a brittle stone and quite pressure sensitive. If you hit an Aquamarine stone off something, you'll notice that splinters start to break off. It is is important to keep this in mind when working with this stone. Aquamarine is also not very heat resistant as the stone can actually change colour when heated. Moreover, the colour may even fade when used normally. It is thus advised to wear Aquamarine in direct sunlight.
Use of Aquamarine beads
Aquamarine beads are mostly used in jewellery. However, they have also been incorporated into crowns, goblets and vases by the Catholic Church. A more practical application is that of contact lenses. Aquamarine, in the 1300's was used for this purpose.
Did you know?
Aquamarine is also found in an opaque (non-transparent) variant. Until recently, this variant was not used for jewellery. This has since changed, though. Nowadays cabochons and beads (cut into different shapes and sizes) are made from transparent Aquamarine.
