1. Aquamarine Means Sea Water
Aquamarine has such an enchanting name. It reminds me of a mermaid with long turquoise hair and piercing blue eyes. Though, the name is based on the old Latin term aqua marīna which roughly translates as water of the sea. Seawater can either depict a dirty, undesirable gulp of saltwater or a crystal clear beach in paradise. I think the latter is a better fit.
2. Aquamarine is the Official Birthstone of March
Aquamarine has been the official birthstone of March since 1912. It is also linked to the 19th wedding anniversary and the zodiac sign Scorpio among others.

3. Sailors Love Aquamarine
Since the days of myths and chariots, aquamarine has been linked to the sea. Sailors would take fancy carved aquamarine pendants and tokens with them on long sea voyages in the hopes that the stone would protect them from seasickness and uncertain death. I know there have been many treasures and jewels uncovered at the bottom of the ocean, but how many of them happen to be aquamarine? If the legend is true, I would guess not too many.
4. Anxiety? Wearing Aquamarine Could Relax You
Not only does aquamarine dispel seasickness and act as a protector on the high seas, but it also is a calming stone used in meditation. The stone is thought to relax the senses and aid in calming the nerves.
5. The Largest Gem-Quality Aquamarine Weighs 244 Pounds
There are a lot of unique famous aquamarine gemstones, and many of them are big and colorful. The largest stone on record weighs 244 pounds and was mined in Brazil in 1910.

6. Aquamarine is Heat Treated
Unfortunately, a lot of aquamarine on the market today is heat-treated. Some stones, like blue topaz, are virtually colorless before they undergo treatment to transform completely into a deep and different color. Aquamarine isn’t like that. The stone comes out of the ground with a particular tone and hue. The stone’s hue doesn’t become deeper or change when it goes through heat treatment. All that happens is that, if successful, all green undertones are removed.
7. Sky Blue is the Most Desirable Shade of Aquamarine
Over the course of aquamarine’s history, the desired shade has varied from turquoise green to sky blue. Right now it seems like the jewelry industry and consumers favor a pure sky blue aquamarine color. Because of this, heat treatment to remove green undertones is so common that it even happens right on-site at the mine before the rough is even cut.
8. Some Aquamarine Loses Its Color in Sunlight
There is a variety of beryl on the market that goes by the name of maxixe aquamarine. This stone comes in a very deep, beautiful blue tone. There’s a catch, though. When this stone is exposed to sunlight, the color slowly fades to light yellowish green. Buyer beware!
9. There are A LOT of Fakes
Even though there are no synthetic aquamarine gemstones on the market, there are a lot of simulated ones. Many of these are marketed as a fancied name aquamarine.

10. Aquamarine is Durable Enough for Engagement Rings

Ranking between 7.5-8 on the Mohs Scale of Hardness puts aquamarine in the “everyday wear” range. Careful, though. Aquamarine can still scratch on its surface, especially by other harder gemstones like sapphire and diamond.
