Aquamarine’s name comes from the Latin for seawater, and this cool-colored stone was said to calm waves and keep sailors safe at sea. The March birthstone, aquamarine was also thought to increase marital happiness. The best gems combine high clarity with transparency and blue to slightly greenish-blue coloration. Aquamarine forms large crystals, which can be used to create sizeable gems for fashionable jewelry.

When shopping for aquamarine gemstones, here is what you need to know:

Look for flawless or nearly flawless stones. Clarity, or the number of inclusions, often determines the quality of a stone. A quality aquamarine should not have any visible imperfections. Low- to mid-range-quality aquamarines can range from $5 to $100 per carat. Larger than 10 carats, mid-range aquamarines can cost between $150 and $200 per carat. High-quality aquamarines are much more expensive. An unheated light blue stone can cost around $90 per carat, while a light blue-green stone can cost between $180 to $240 per carat.

Choose the blue for you. Stones that are richly blue-colored are typically more valuable (and expensive) than those with more green hues. Most blue-green aquamarine gems are more valuable than borderline-clear stones. Ultimately, however, the right hue is a matter of personal preference.

Don’t fear the heat. Heat treatment is a widely accepted practice used to enhance the blueness of a stone. Yellow-brown and yellow-green stones are heated to a temperature between 400 and 450 degrees Celsius, or 752 and 842 degrees Fahrenheit. This treatment is permanent and does not damage the stone, but it does create more beautiful stones at a lower price point. The most expensive unheated stones are medium to strong sky blue, and they can cost up to $550 and $600 per carat. Heated aquamarines with a strong blue-green hue are less expensive and can cost approximately $180 per carat.

 Be mindful of masqueraders. Blue topaz is considerably less valuable than aquamarine, but the two stones can look very similar. If you are shopping for true aquamarine, steer clear of gemstones labeled as “Brazilian aquamarine” or “Nerchinsk aquamarine,” since both of these actually refer to blue topaz. Also avoid “Siam aquamarine,” which is actually blue zircon.
