Natural Aquamarine

Aquamarine is the sky blue or turquoise colored variety of beryl. It is one of the most popular and important gemstones, well known for its exceptional clarity and the large sizes it may occur in. The name Aquamarine is derived from Latin: aqua marina, "water of the sea". It occurs at most localities which yield ordinary beryl.

Almost as popular as the classics… ruby, sapphire and emerald, the color of aquamarine ranges from a light greenish blue to a deeply saturated tropical ocean teal blue. The best colors are darkest and aquamarine is never too dark. In the trade, the top color is known as “Santa Maria” … the color of the stones from the Santa Maria de Itabira mine in Brazil where that color was first discovered. But fine aquamarines equaling or even surpassing the “Santa Maria” are also found in other localities in Madagascar, Mozambique, Sri Lanka and South India.

Aquamarine Aquamarine Aquamarine Aquamarine
Aquamarine is well known to occur in large and even extremely large sizes and some sensationally large aquamarine crystals have been found such as the crystal of 110.5 Kg found in 1910 in Marambaia/Minas Gerais and the 26kg 'Dom Pedro' aqua fashioned in Idar-Oberstein by the famed gemstone designer Bernd Munsteiner. The Dom Pedro is largest aquamarine ever to have been cut and is now housed in the Smithsonian Institution's National Museum of Natural History in Washington.

Aquamarine is a favorite stone of modern designers. It is remarkably clean and often free of inclusions and even the lightest colors will produce attractive brilliant stones. Whether fashioned as a clear, transparent gem in a classical step cut, or creatively cut with fine grooves, notches, curves, and edges, it is always fascinatingly beautiful. Even uncut, or with many inclusions it can be refined to produce the most beautiful creations.

Some aquamarines are heated and it is relatively easy to heat the light greenish stones at low temperatures to make them light blue. The treatment may not be possible to detect but in any case, it is accepted and usually increases the value of the stones.

Aquamarine prices are primarily a function of their color and subtle differences in hue and tone will markedly affect the value of the material. Dark aquamarines are considered to be the most valuable. It is commonly heated to decrease the green and enhance the blue. The treatment is generally accepted in the trade and is permanent.

Aquamarine, the "gem of the sea" is the birthstone for March. Legends say that it is the treasure of mermaids, with the power to keep sailors safe at sea. Aquamarine protects against the wiles of the devil. A dream of aquamarine means that you will meet new friends. Aquamarine is an ideal gemstone – hard, very clean, always attractive, available in large sizes, easy to fashion yet still affordable for most buyers of jewelry or gemstones.
