An engagement ring is forever, so it should have timeless style and plenty of character that makes it uniquely yours. That's what makes aquamarine engagement rings so popular among couples looking for beautiful, stand-out bling that won't go out of style. The gemstone's distinct blue color—a light greenish-blue—is stunning enough on its own as well as in combination with white diamonds or other gemstones. Even celebs are falling for aquamarine engagement rings. Jessica Biel's six-carat stunner, for example, features a diamond center stone flanked by aquamarines. What's more, the gemstone carries with it plenty of symbolism and historical significance.

Here's everything you need to know to choose the best aquamarine diamond engagement ring for you.

What Is Aquamarine?

Known as the "gem of the sea," aquamarine's name comes from the Latin phrase aqua marinus, meaning seawater. The light blue stone is part of the beryl family of gemstones that also includes emeralds.

Because of its distinct color—due to the presence of iron in its chemical composition—and transparency reminiscent of the sea, the ancient Greeks and Romans considered aquamarine a sailor's gem that could protect seafarers against shipwrecks and other perils. In modern day, those who have a special relationship with the ocean will surely appreciate the gemstone's connection to the seas. Fun Fact: According to one legend, the blue gemstone was also believed to be mermaid treasure.

Aquamarine has been a favorite of jewelers for thousands of years. It's especially popular as an engagement ring because it's associated with long relationships, harmony and clarity. It's also the birthstone of March.

What to Look For in an Aquamarine Engagement Ring

Not all aquamarines were created equal. In fact, there are even variations in its blue color. Aquamarines in deeper and darker shades of blue are considered more valuable than lighter blue ones because they're more rare.

It's also common practice for manufacturers to enhance the color of the gemstones by heating them. This treatment permanently changes the color of the stone without damaging it. Most mined aquamarines actually have a greenish-blue color, so some manufacturers heat the stones to remove the green tint. Pro tip: It's essential to purchase your engagement ring from a trusted seller who will disclose any additional treatments the stone may have been subject to.

Like diamonds, aquamarines can be cut into any shape, which is another reason the gemstone is so popular. Take a good look at the stone before buying the ring to make sure it is also correctly faceted.

And finally, look for any internal flaws or irregularities in the stone. Because of aquamarine's natural clarity, those shouldn't be difficult to spot even if you're not a pro.

Why Choose an Aquamarine Engagement Ring?

Aquamarines add a delicate splash of color to engagement rings making for a unique appearance. But looks aside, choosing this particular gemstone has a few practical benefits, too.

First, though it's a semi-precious gem, aquamarine is durable enough to withstand constant wear. It scores 7.5 to 8 on the Mohs hardness scale (a diamond is a 10), making it pretty resistant to scratches and breakage. Of course, you should still be careful not to hit it against hard surfaces, as you may chip it.

In terms of cleaning and maintenance, aquamarine doesn't require anything out of the ordinary. Just clean the ring with a soft cloth and soapy water, and take it to your jeweler once a year for a professional inspection and cleaning.
