Aquamarine is best known for its breathtaking range of blue colours and belongs to the same family as emerald (beryl). The name derives from the Latin expression for seawater. Aquamarine is coloured by trace amounts of iron that find their way into the crystal structure. A dark blue is the most desired colour. Aquamarine possesses a durable hardness (7.5-8 on the Mohs scale), which qualifies it for any kind of jewellery.
The favoured cuts are emerald (step) and brilliant cut with long or rectangular shapes. Turbid stones get a cabochon cut. Aquamarine is a decorative gem that complements almost any skin or eye colour, which makes it an all-time favourite for women the world over. It is a popular gem, universal to wear, readily available and moderately priced, but growing in popularity.
