Possess the powers of the sea. Its Latin name is ‘aqua marinus’, which means ‘water of the sea’ and refers to its blue-green color. Previously it was thought that the stone was associated with mermaids, and it was used as a lucky charm by sailors. It soothes the soul and strengthens truth and trust. To make the aquamarine shiny again, clean it with lukewarm water and mild soap – maybe use a soft brush like a toothbrush to clean it. Rinse and dry carefully.
