precious stones: Aquamarine

Aquamarine is a precious stone that is known for its beautiful blue-green color and its association with the sea. In this article, we will explore the history, properties, and uses of aquamarine.


Aquamarine has been known and valued for thousands of years. The ancient Greeks and Romans believed that it had the power to calm the waves and protect sailors at sea. The name "aquamarine" comes from the Latin word "aqua," which means "water," and "marina," which means "of the sea."

Aquamarine is found in many parts of the world, including Brazil, Madagascar, and the United States. It has been used in jewelry and other decorative items for centuries.


Aquamarine is a member of the beryl family of minerals, which also includes emerald and morganite. The color of aquamarine is caused by the presence of iron within the crystal structure, and can range from pale blue to deep blue-green. The most valuable and sought-after color of aquamarine is a deep blue-green.

Aquamarine is a relatively hard stone, with a Mohs hardness rating of 7.5 to 8 out of 10. It is not as hard as diamonds, but it is still very durable and resistant to scratches and damage. Aquamarine also has a high refractive index, which gives it a brilliant sparkle and shine.


The most common use of aquamarine is in jewelry. It is often used in necklaces, earrings, and bracelets, and is particularly popular in engagement rings. Aquamarine is often paired with diamonds and other gemstones, as its blue-green color complements many other colors well.

In addition to its use in jewelry, aquamarine is also used in industry. It is used as a component in electronics and in the manufacture of certain kinds of glass. Aquamarine is also sometimes used in water filtration, as it can be used to remove impurities and contaminants.
