The Aquamarine is a gemstone known for its captivating blue, 'sea-water' colour. The Aquamarine was known by legend to belong in the treasure chests of mermaids at the bottom of the ocean. It was also considered the 'lucky gemstone' by sailors who would wear it around their necks. Like the Emerald, the Aquamarine is made from Beryl. The colour is owed to pieces of divalent iron within the structure of the crystal. Larger crystals tend to have stronger colours and deeper blues, with the smaller ones looking more pale and watery. While Brazil is known for finding Aquamarine crystals, other countries such as Zambia, Nigeria, Pakistan and others have made findings.
