If you think Aquamarine is the one and only blue-green gemstone** reigning over the mineral world, I’m about to change that perspective—and you’ll thank me later.

Blue and green stones have been coveted for centuries, symbolizing the ocean, tranquility, and limitless horizons. While Aquamarine is one of the most well-known, there are many other gems that share similar hues, textures, and compositions—each with its own unique personality.

From the deep tropical blues of Larimar to the electric vibrancy of Apatite, this guide will break down 20 blue-green gemstones, helping you tell them apart and appreciate what makes each one special.

1. Aquamarine: The Ocean’s Crystal

Let’s start with the star of the show.

Aquamarine, the March birthstone, is a variety of beryl, ranging from pale sky blue to deep seafoam green. It gets its color from iron impurities and is prized for its clarity and transparency. Unlike most blue-green stones, Aquamarine is nearly flawless, with a crystal-clear serenity that mimics tropical waters.

• Hardness: 7.5 – 8 (Mohs scale)
• Color Range: Pale blue, seafoam green, teal
• Origin: Brazil, Madagascar, Pakistan

Fun Fact: Ancient sailors carried Aquamarine as a talisman against rough waters, believing it was treasure from mermaids.

How to Tell It Apart: If it looks like pure, undisturbed ocean water in a gemstone—it’s Aquamarine. Its lack of inclusions and high transparency distinguish it from other blue-green stones.

Frequently Asked Questions

Q: Why does my aquamarine stone look greener or bluer than others? 

The color of aquamarine depends on how much iron is present in the crystal. It also varies by whether the stone has been heat-treated, which often enhances its blue hue. You'll find that natural aquamarines can range from a soft, pale blue to a seafoam green.

Q: How can I tell if a gemstone is aquamarine or something else? 

Aquamarine typically appears as a transparent stone with a gentle, pale blue or seafoam green hue. It has a nice, glassy luster and is quite durable. If you want to be sure, a gemologist can confirm its identity using specialized tools and techniques like checking the refractive index or using spectroscopy.

Q: How does aquamarine compare to teal tourmaline in terms of color and clarity?

Aquamarine is typically lighter and more transparent, often showcasing a soft sky-blue hue. On the other hand, teal tourmaline can be darker and has a richer color, which sometimes makes it less transparent.

Q: Does aquamarine change color over time like some other gemstones?

Aquamarine is pretty stable and doesn't usually change color with time or light exposure. However, some varieties that have been irradiated to enhance their blue hues can fade if exposed to excessive light. It's also wise to keep it away from extreme heat and harsh chemicals, as those can damage the stone or its setting.

Q: Is aquamarine more valuable than other blue-green gemstones? 

Yes, aquamarine is usually more valuable than stones like turquoise, amazonite, or apatite, especially when it's clean, transparent, and richly colored.

Q: Which is more durable: aquamarine, turquoise, or amazonite? 

When it comes to durability, aquamarine takes the lead. It ranks between 7.5 and 8 on the Mohs scale, making it quite tough. In contrast, turquoise and amazonite are softer, scoring 5 to 6 and 6 to 6.5, respectively.
