The word is derived from the Latin AQUAMARE, which means water of the sea. It is renowned for its crystal blue colours and its excellent clarity. It is also known as the emerald's sister stone. While both stones are of the beryl family, aquamarine possesses a delicate, light blue hue reminiscent of the ocean’s calm.
