Aquamarine is an almost clear, pale blue form of beryl, the same family of stones from which emeralds originate. Legend says that it is the treasure of mermaids and in ancient times sailors often carried aquamarine to protect them against drowning.
It is thought to be a calming stone which helps to quieten the mind and instil serenity, whilst promoting courage and strength. It is also believed to help when dealing with difficult situations. As well as being the birthstone for March, it is also the 19th anniversary traditional gemstone.
