If a person had hiccups, for example, people believed that this could be cured by drinking water in which an aquamarine had been placed. It was believed that aquamarines held healing properties as well as contained magical elements. The word aquamarine comes from the Latin word for seawater due to its colour. Due to having the same color aquamarine can be confused with euclase, topaz (dichroism -having two color- is one of the optical differences between aquamarine and blue topaz), tourmaline, zircon, and kyanite. Aquamarine, unlike emerald and bixbite, commonly occurs with few or no noticeable inclusions. It weighed over 240 pounds and was cut into more than 100,000 carats of gem. The largest known gem-quality aquamarine was found in 1910 in Minas Gerais, Brazil. Gem-quality aquamarine is found as hexagonal crystals, which may be up to 1m long and flawless, with striations along the length of the crystal. Aquamarine is dichroic ( two-coloured), appearing blue or colorless depending on what angles the gemstone is viewed. Its color varies from light blue to deep blue due to presence of small amount of iron. Aquamarine is Latin for water of the sea and it is named because of its sea water color( aqua Latin for water and mare Latin for sea). Aquamarine belongs to the Beryl gemstone family (blue Beryl) with Beryllium Aluminum Silicate chemical composition.
