Aquamarine, from the Latin aqua marina, is a blue-greenish variety of beryl that makes it similar to the color of the sea water. The coloring is very varied: from sky-blue of different shades to sea-green. The pale blue color is attributed to iron oxides and not for chromium oxides as in emerald; unlike the latter, the coloring is generally evenly distributed.The aquamarine crystals are prismatic and often of considerable size; specimens of 2-3 cm in length and width, pure and beautiful in color, are not uncommon; they are generally rich in faces, as well as for all the other varieties of beryl, except for the emerald. Gems are generally flawles, and there are no inclusions and cracks as described in the emeralds, except for some slight inclusions made up of micaceous lamellae, by small crystals that can produce the typical effect called chatoyancy.
Aquamarine is mainly found in granite pegmatites but thanks to its high hardness and specific gravity it is also possible to find it in palcers in Sri Lanka. The most important deposit where aquamarine is mined is located in the state of Minas Gerais, in Brazil. Other important deposits are located in Russia, Madagascar, Pakistan and Mozambique. Huge crystals are found in the latter.
This mineral, thanks to its purity and transparency, proves to be very suitable for instilling tranquility, relief and comfort. Helps the spirit in difficult moments and purifies it removing fears, phobias and states of anxiety. Aquamarine is considered to be suitable to cure all inflammatory states  such as laryngitis, sore throat or chronic allergic states. It can also alleviate tired eyes if placed on the eyelid for about twenty minutes every evening.
