Aquamarine has long been associated with tranquility and happiness, but also has been ascribed the ability to cure laziness and sharpen the intellect. Like the sea, aquamarine's attributed qualities can be soothing but can also froth with the changing of the tides. This lovely stone was also thought to instill courage and be lucky to sailors.
As a member of the beryl family, aquamarine is frequently free of flaws and may occur in very large crystals. Depending on its size and purity of color, aquamarine can be a vibrant blue-green to an almost colorless pale blue. The more intense the color, the more valuable the stone is. Lighter versions are more common than pure, clear vivid blue aquamarine and therefore the brighter stones are more sought after and popular.
On the Mohs scale, aquamarine ranks as a 7.5 to 8 for hardness. The stone is found in many countries such as Colombia, Norway, Germany, Ireland, Brazil, the United States, and Mozambique. In 1910, the biggest gemstone-quality aquamarine every found was mined in Minas Gerais, Brazil. The impressive stone was 19 inches long, 17 inches in diameter, and weighed over 200 pounds!
