Aquamarine Stone Benefits and Uses

History and Facts of Aquamarine Stone

Derived from the Roman word “aqua,” meaning water” and “mare” meaning sea, Aquamarine Stone gem does indeed resemble the color of seawater.

A member of the beryl family, it was first mined in 1811 in Brazil, but the earliest documented use of an aquamarine gemstone is by the Greeks, around 480 to 300 BC.

Aquamarine stone occurs primarily in granite pegmatites and to a lesser extent in granite vugs.

It is also in hydrothermal carbonate veins and greisens.

It is typically associated with quartz, feldspars and muscovite, and often occurs with other common pegmatite minerals such as biotite, garnet, phenakite, and topaz.

Because of aquamarine’s relatively high hardness and specific gravity, it is sometimes found in eluvial and alluvial deposits.

Crystals are often elongated along the c-axis creating the effect of appearing wand-like or pencil-like.

Aquamarine stone is known for having long, hollow tubes. Though rare, if there are enough of these hollow tubes, chatoyancy or asterism (also known as cat’s eyes or stars) can be produced with proper cutting.

The name aquamarine has been used as a modifier for many other materials such as aquamarine tourmaline, aquamarine emerald, aquamarine chrysolite, aquamarine sapphire, aquamarine topaz, etc.

It has even been used to describe the sea, the skies, some General Motors cars, or other pale to medium blue objects.

Aquamarine Stone Colors

Aquamarine stone is pastel blue, greenish-blue, or green-blue.

The preferred aquamarine color is a dark blue to slightly greenish blue with moderate intensity and is most striking in gems of over 5 carats.

Fine stones show even blue color with no zoning.

Benefits of Aquamarine Stone

Lore attributes the power of foresight, happiness, and courage to those who wear an aquamarine stone.

It is considered a symbol of honesty, beauty, and loyalty, and both increase intelligence and extend youth.

In alternative healing, aquamarine is considered to be an effective healing stone for anxiety and insomnia.

In the Middle Ages, aquamarine was also thought to have a poison-reducing effect.

It is said that aquamarine stone is particularly powerful when immersed in water which is bathed in sunlight.

Water in which this gemstone had been submerged was used in ancient times to heal a variety of illnesses of the heart, liver, stomach, mouth, and throat, as well as, cure hiccups.

This gemstone has been called the “treasure of mermaids”, with the power to keep sailors safe at sea.

Sailors once believed that carrying an aquamarine would bring good luck and safety on the seas and protection against seasickness, especially if the stone was engraved with the Poseidon chariot.

A dream of aquamarine was said to mean you would meet new friends.

Over the centuries, the gemstone has been said to protect against the “wiles of the devil”; to wit, when held in the mouth, the aquamarine stone could enable one to call a devil from hell and receive answers to any questions asked.

Though aquamarine gemstones are not completely flawless, they do not have many natural inclusions.

The transparent rough crystals are usually “eye clean”.

The most common eye visible inclusions are raindrop-like needles which can be seen under magnification.

Inclusions in aquamarine may include mica, hematite, liquid-filled (often salt-water) tubes, and hoses.

The liquid can expand considerably if the crystals become overheated, causing them to fracture badly, or in rare instances, to explode.

Beware of misleading retail labels. “Brazilian Aquamarine” is blue topaz. Also, a gemstone known as “Siam Aquamarine” is heat-treated blue zircon.

Because aquamarine gemstones commonly occur in large clean crystals, the size of the finished stone is not an important evaluation characteristic.

The price is dependent on its clarity and the depth of color. For example, a 40 carat very pale aquamarine gem will be worth the same as a very fine deep blue aquamarine of one-carat size.

Aquamarine stone has been the traditional birthstone for March although some jewelers’ charts list bloodstone as an alternate.

Aquamarine Cut

Aquamarine stone can be cut into almost any shape, but cutters often fashion them as emerald cuts or as round or oval brilliants.

Many gem artists use aquamarine for one-of-a-kind designer cuts because their styles maximize the material’s pure, even color, and high clarity.
