Aquamarine is a member of the beryl family

Like emerald, aquamarine is a member of the beryl family (along with morganite, heliodor, and others). Unlike emerald, it is frequently free of flaws and often occurs in large crystals. Aquamarine’s main pigment comes from iron. The color spectrum of aquamarine varies from very pale blue to a deep blue, the finest specimens being the deepest in color.

Most aquamarine stones have a subtle green component, and in some markets, a deep greenish blue is the most desirable.

Brazil is the most prolific supplier of aquamarine where it is often found in shades of blue-green.

Aquamarine has a refractive index of 1.577 to 1.583 and is doubly refractive. Aquamarine’s specific gravity is 2.72 and it has a Mohs hardness of 7.5-8.0. For comparison, this means that it is softer than Sapphire, harder than Quartz, and similar to Topaz. This makes it a very durable stone that is suitable for regular wear. But, care should still be taken to ensure that the stone is not damaged.

Caring For and Cleaning Aquamarine

To maintain the brilliance of this beautiful gemstone, it should be immersed in jewelry cleaner or in lukewarm soapy water and cleaned with a small bristle brush. Don’t use ultrasonic cleaners on aquamarine. Since aquamarine is not typically very vibrant in color, it can look more dull if it gets dirty. If you notice that your stone isn’t looking quite as brilliant as you remember, it might just be dirty. You can try cleaning it at home or bringing it in to your local jeweler for a more professional cleaning.

While aquamarine is a durable gemstone it is still vulnerable to damage from knocks against hard objects when being worn. Take off your aquamarine jewelry when doing household chores, going to the gem, or otherwise working with your hands.

With proper care a piece of aquamarine jewelry can last generations being handed down and treasured for years to come.
