Aquamarine is a beautiful gemstone known for its stunning blue color. It is a member of the beryl family, which also includes emerald and morganite. Aquamarine is popular in jewelry, and its price can vary widely depending on several factors. In this article, we will explore the price of aquamarine per carat in detail. We will look at what makes aquamarine valuable, how its price is determined, and what you can expect to pay for this gemstone.
What is Aquamarine?
Aquamarine is a blue or blue-green gemstone. Its name comes from the Latin words “aqua” (water) and “marina” (sea), which means “water of the sea.” This name reflects its beautiful ocean-like color. Aquamarine is a durable gemstone, with a hardness of 7.5 to 8 on the Mohs scale. This makes it suitable for everyday wear in jewelry like rings, necklaces, and earrings.
Aquamarine is found in many parts of the world, including Brazil, Madagascar, Nigeria, and Pakistan. Brazil is the largest producer of high-quality aquamarine. The gemstone is often found in large crystals, which means it can be cut into large, eye-clean stones. This is one reason why aquamarine is relatively affordable compared to other gemstones like sapphire or emerald.
Factors That Affect the Price of Aquamarine
The price of aquamarine per carat depends on several factors. These include color, clarity, cut, carat weight, and origin. Let’s look at each of these factors in detail.
Color
Color is the most important factor in determining the price of aquamarine. The most valuable aquamarines have a pure, intense blue color. Some aquamarines have a slight greenish tint, which is less desirable. The ideal color is often described as “sky blue” or “ocean blue.”
The color of aquamarine is graded on a scale from light to dark. Light blue aquamarines are less expensive, while medium to dark blue stones command higher prices. However, if the color is too dark, it can look less attractive, and the price may drop.
Clarity
Clarity refers to the presence of inclusions or imperfections in the gemstone. Aquamarine is known for its high clarity, and most stones are eye-clean, meaning they have no visible inclusions when viewed with the naked eye.
Stones with high clarity are more valuable. However, some aquamarines may have inclusions like liquid-filled cavities or tiny mineral crystals. These inclusions can lower the price, especially if they are visible or affect the gemstone’s durability.
Cut
The cut of an aquamarine affects its brilliance and overall appearance. A well-cut stone will reflect light beautifully, enhancing its color and clarity. Aquamarine is often cut into oval, round, or emerald shapes. It can also be cut into fancy shapes like pear, marquise, or cushion.
The quality of the cut is important. A poorly cut stone may look dull or uneven, which can lower its value. On the other hand, a well-cut aquamarine will have good symmetry, proportions, and polish, making it more valuable.
Carat Weight
Carat weight refers to the size of the gemstone. Larger aquamarines are rarer and more expensive per carat than smaller stones. However, the price per carat does not increase linearly with size. For example, a 10-carat aquamarine will cost more per carat than a 1-carat stone.
Aquamarine is often found in large crystals, so it is possible to find large stones at relatively affordable prices. However, very large stones with excellent color and clarity are still rare and can be quite expensive.
Origin
The origin of an aquamarine can also affect its price. Some locations are known for producing high-quality stones. For example, aquamarines from Brazil, especially the Santa Maria mine, are highly prized for their intense blue color. Aquamarines from Madagascar and Nigeria are also known for their quality.
Stones from famous mines or regions may command higher prices due to their reputation and rarity. However, origin is less important than color, clarity, and cut when determining the value of an aquamarine.
Price Range of Aquamarine Per Carat
The price of aquamarine per carat can vary widely depending on the factors mentioned above. Here is a general guide to the price range:
- Low-Quality Aquamarine: 10to50 per carat
These stones have a light blue or greenish color, visible inclusions, and a poor cut. They are often used in mass-produced jewelry. - Medium-Quality Aquamarine: 50to200 per carat
These stones have a medium blue color, good clarity, and a decent cut. They are suitable for everyday jewelry and are popular in mid-range designs. - High-Quality Aquamarine: 200to500 per carat
These stones have a deep, intense blue color, excellent clarity, and a well-proportioned cut. They are often used in fine jewelry and can be quite expensive. - Top-Quality Aquamarine: 500to1,000+ per carat
These stones are rare and have a pure, vivid blue color, flawless clarity, and an exceptional cut. They are often used in high-end jewelry and can be very expensive, especially in larger sizes.
It’s important to note that these prices are approximate and can vary depending on the market, the seller, and other factors. For example, a large, top-quality aquamarine from a famous mine may sell for thousands of dollars per carat at auction.
How to Buy Aquamarine
If you are interested in buying aquamarine, here are some tips to help you get the best value for your money:
Choose the Right Color: Look for a stone with a pure, intense blue color. Avoid stones with a greenish tint unless you prefer that look.
Check the Clarity: Most aquamarines are eye-clean, but it’s still a good idea to examine the stone under a magnifying glass to check for inclusions.

Ask About Origin: While origin is not the most important factor, stones from famous mines like Santa Maria in Brazil may have a higher value.
