Aquamarine

Named after seawater, aquamarine’s fresh watery hue is a cool plunge into a refreshing pool.

Aquamarine Description

Aquamarine is the green-blue to blue variety of the mineral beryl. (Emerald is the green to bluish green variety of the same mineral.) Its color is usually a light pastel greenish blue.

Heat treatment usually gives it a more bluish appearance.

Aquamarine crystals are known to be large in size and relatively clean and well-formed, making them particularly valuable to collectors of mineral specimens.

Aquamarine History and Lore

Aquamarine’s name comes from the Latin for seawater and it was said to calm waves and keep sailors safe at sea. March’s birthstone was also thought to enhance the happiness of marriages. The best gems combine high clarity with limpid transparency and blue to slightly greenish blue hues. Like many beryls, aquamarine forms large crystals suitable for sizable fashioned gems and carvings.
