Aquamarine fascinates like the bottomless waters of tropical seas. Even Roman astrologers dedicated it to the sea god Neptune. They put in the name of the mineral both concepts - water and sea (aqua + mare). But the blue stone also resembles the azure of the sky.
Aquamarine is a clear crystal that has a bluish-green tone. It shows highlights of different shades at different angles. If to change it, the color of the gem will also change.
