Aquamarine, March's Birthstone
An aquamarine is a very hard stone, ranging on the Mohs scale at 7.5 to 8. The hardness of the stone makes it more durable and less likely to scratch.
The best way to clean an aquamarine is with warm, soapy water and an old toothbrush. Be sure to rinse the soap away thoroughly. Be sure to use warm water and not hot. The extreme in temperature for aquamarines, and many other gemstones, can damage the stone. It is best to avoid harsh chemicals and household detergents. An ultrasonic cleaner is also not advisable.
The best quality aquamarines come from Brazil. There stones weighing up to several kilos have been found. Other areas include Nigeria, Zambia, Madagascar, the Soviet Union, Afghanistan, Pakistan, India and the United States.
