March Birthstone - Aquamarine

March’s stone is the aquamarine. Aquamarine is a member of the beryl family of stones and ranges in color from a nearly colorless pale blue to a rich blue-green/teal color. In the 19th century, sea green varieties of the stone were the most highly desired, but now, the most valuable shade for an aquamarine is a deep-blue aqua color. The name comes from the Latin words “aqua marina” which translates to “sea water”.

A roman history of aquamarine

The aquamarine was one of the most popular jewels adorned by Roman citizens in ancient times. Aquamarine jewelry was one of the most common wedding gifts from a husband to his bride, as husbands believed that the stone absorbed the atmosphere of young love.

The Romans also believed that if an aquamarine had the carving of a frog inscribed on it that it would help enemies mend their differences and become friends.

Roman and Greek sailors both believed the aquamarine to be a stone that would ensure safety and prosperity during stormy seas. It was also commonly worn by soldiers under the belief that it made soldiers invincible in battle and would lead to certain victory.

One of the most important mystical stones during the Middle Ages, the aquamarine was commonly cut into the form of a crystal ball and used by mystics (including the famous Dr. John Dee, who used it to determine the best coronation date for Queen Elizabeth I). During this time, the aquamarine was also believed to have the ability to rejuvenate the love of married couples and was believed to be an antidote to poisons. Because of the frequency of poisonings amongst royalty, the aquamarine became a very sought after stone. While other stones needed to be ground into a powder and ingested to fight poison, the aquamarine would provide the same results while simply being worn in jewelry.

The aquamarine was also perceived as the cure to belching and yawning. It was considered to be an effective treatment for ailments of the jaw, throat, liver, stomach, and toothaches. The gem was even used in ceremonies to bring about rain when needed, or to bring about drought to one’s enemies. Wearing aquamarine as an amulet was said to cure laziness, reduce anxiety, quicken intellect, and to make the wearer friendlier.
