Aquamarine originated in the 1820s from a Latin term aqua marina which means sea water. This popular gem has been by Indians as a good luck charm. Legend has it that the gem was a treasure of mermaids. Aquamarine is found in Brazil and the African countries of Tanzania, Kenya and Nigeria, the island of Sri Lanka, Afghanistan and Russia. Aquamarine is usually heat treated to remove the yellow components to make it bluer. Aquamarine has even been thought to help cure headaches, insomnia and other such ailments. This gem is given on the 19th wedding anniversary as a sign of love.
