How Much is an Aquamarine Worth? An In-Depth Guide to Aquamarine Value

With its captivating blue hues reminiscent of the ocean, aquamarine is a gemstone prized for its serene beauty. From ancient times to modern day, this enchanting beryl variety has been treasured in jewelry and lore. But what is aquamarine truly worth? Let‘s dive deep into the many factors that determine the value of this mesmerizing gem.

The Allure of Aquamarine: Color, Composition, and History

The name "aquamarine" comes from the Latin words for water (aqua) and sea (mare) – a fitting description for its signature blue-green color. Aquamarine is a type of beryl, a mineral composed of beryllium aluminum silicate. It gets its hue from trace amounts of iron and forms in metamorphic rocks and granite pegmatites.

Throughout history, aquamarine has been imbued with rich symbolism. Ancient Romans believed it could protect sailors at sea, while in medieval times it was thought to reawaken love in married couples. Today, it remains associated with tranquility, courage and clarity.

The largest aquamarine deposits are found in Brazil, Pakistan, and African countries like Nigeria, Madagascar and Mozambique. Gems are fashioned into many shapes, but emerald and oval cuts are most common to maximize color.

Evaluating Aquamarine Quality and Value

As with other colored gemstones, aquamarine value is determined by the "four Cs" – color, cut, clarity and carat weight. Understanding these quality factors is key to assessing an individual stone. Let‘s break them down:


Color is the most important value factor for aquamarine. The most desirable hue is a pure, intense blue with no green tint or gray mask. Stones can range from very light to very deep blue, with medium tones considered ideal. Generally, the more saturated the blue color, the more valuable the gem.


Skilled cutting is essential to bring out aquamarine‘s best color and brilliance. Well-proportioned facets and symmetry can make a huge difference in a stone‘s beauty and value. Oval and emerald cuts are popular, as are round, pear, and cushion shapes. Cabochons and carved gems are also available.


Most cut aquamarines are eye-clean, meaning they have no visible inclusions when viewed by the naked eye. Even very lightly included stones are acceptable. However, large, dark or numerous inclusions can lower value significantly. Any haziness or cloudiness also detracts.

Carat Weight

Aquamarine is known for large crystals, so bigger stones are relatively common compared to other gems like ruby or sapphire. Still, prices do rise substantially per carat as size increases. Typical cut gems weigh under 5 carats, but stones over 10-25 carats are seen in designer jewelry.

Natural vs Lab-Grown

It‘s important to know whether an aquamarine is earth-mined or created in a lab. Synthetic aquamarine has been produced for decades and has the same chemical and optical properties as its natural counterpart. However, lab gems usually sell for significantly less than mined aquamarines of similar appearance. Always ask if a stone is natural or lab-grown.

Aquamarine Price Guide

Putting it all together, what kind of prices can you expect for aquamarine? Here are some typical ranges for faceted stones:

  • Lower-quality (lighter color) – $5 to $100 per carat
  • Medium-quality (moderately intense blue) – $100 to $250 per carat
  • Higher-quality (vivid, deeper blue) – $250 to $1,000+ per carat, with an average around $675/ct for fine stones

Note that prices can climb much higher for rare, top-color Brazilian gems in large sizes. Always judge an individual stone by its specific qualities.

When buying aquamarine jewelry, prices depend on the center stone as well as the precious metal and any accent gems. A 14K gold ring with a 1-2 ct medium-blue aquamarine might cost $500-$1000, while a designer piece with a 5 ct+ vivid blue gem could run well over $5,000-$10,000.

Where to Buy Aquamarine
