Aquamarine is a beautiful gemstone that has been cherished for centuries. Its name comes from the Latin words “aqua” (water) and “marina” (sea), which perfectly describe its stunning blue-green color. This gemstone is a member of the beryl family, which also includes emerald and morganite. Aquamarine is known for its clarity, durability, and soothing color, making it a popular choice for jewelry. But how much is aquamarine worth per carat? In this article, we will explore the factors that influence the value of aquamarine, its market trends, and what you should know before buying or selling this gemstone.
What is Aquamarine?
Aquamarine is a blue to blue-green variety of the mineral beryl. Its color ranges from pale blue to deep blue-green, and it is often associated with the ocean. The gemstone is found in many parts of the world, including Brazil, Madagascar, Nigeria, Pakistan, and Mozambique. Brazil is the largest producer of high-quality aquamarine, and some of the most famous aquamarine gemstones have come from Brazilian mines.
Aquamarine is a relatively hard gemstone, with a rating of 7.5 to 8 on the Mohs scale of hardness. This makes it durable enough for everyday wear in jewelry, such as rings, earrings, necklaces, and bracelets. Its clarity is another attractive feature, as most aquamarines are eye-clean, meaning they have no visible inclusions to the naked eye.
Factors That Influence the Value of Aquamarine Per Carat
The value of aquamarine per carat depends on several factors, including color, clarity, cut, carat weight, and origin. Let’s break down each of these factors in detail.
Color
Color is the most important factor in determining the value of aquamarine. The most desirable color is a pure, intense blue with no green or gray undertones. However, the color of aquamarine can vary widely, from pale blue to deep blue-green. Generally, the deeper and more saturated the color, the higher the value.
- Pale Blue Aquamarine: These stones are lighter in color and are often more affordable. They are still beautiful but are less valuable than deeper blue stones.
- Medium Blue Aquamarine: These stones have a more noticeable blue color and are more valuable than pale blue stones.
- Deep Blue Aquamarine: These stones are the most valuable because of their rich, intense color. They are rare and highly sought after.
The presence of green or gray undertones can lower the value of aquamarine. However, some people prefer a slight greenish hue, as it gives the stone a more natural, oceanic appearance.
Clarity
Aquamarine is known for its excellent clarity. Most aquamarines are eye-clean, meaning they have no visible inclusions when viewed with the naked eye. Stones with high clarity are more valuable because they allow light to pass through easily, enhancing their brilliance and sparkle.
Inclusions, such as tiny cracks or mineral deposits, can lower the value of aquamarine. However, some inclusions are acceptable as long as they do not affect the stone’s overall appearance or durability.
Cut
The cut of an aquamarine can greatly affect its value. A well-cut stone will have excellent proportions, symmetry, and polish, which enhance its color and brilliance. Aquamarine is often cut into oval, round, or emerald shapes, but it can also be cut into fancy shapes like pear, marquise, or cushion.
The cut should maximize the stone’s color and minimize any visible inclusions. Poorly cut stones may appear dull or lifeless, which can lower their value.
Carat Weight
Aquamarine is available in a wide range of sizes, from small stones to large, impressive gems. Larger stones are rarer and more valuable, especially if they have excellent color, clarity, and cut. However, the price per carat does not increase linearly with size. For example, a 10-carat aquamarine may be significantly more expensive per carat than a 1-carat stone.
It’s important to note that larger aquamarines are more likely to show color zoning, which is when the color is unevenly distributed throughout the stone. This can affect the stone’s overall appearance and value.
Origin
The origin of an aquamarine can also influence its value. Some locations are known for producing high-quality stones with desirable colors. For example:
- Brazil: Brazilian aquamarines are highly prized for their deep blue color and excellent clarity. The Santa Maria mine in Brazil is famous for producing some of the finest aquamarines in the world.
- Madagascar: Aquamarines from Madagascar are known for their rich blue color and high clarity.
- Nigeria: Nigerian aquamarines often have a slightly greenish hue, which some people find appealing.
- Pakistan: Pakistani aquamarines are known for their pale blue color and high clarity.
Stones from famous mines or regions may command higher prices due to their reputation and rarity.
Market Trends and Pricing
The price of aquamarine per carat can vary widely depending on the factors mentioned above. On average, aquamarine prices range from 50to500 per carat. However, exceptional stones with deep blue color, high clarity, and large carat weight can fetch prices of $1,000 or more per carat.
Here’s a general price guide based on quality:
- Low-Quality Aquamarine: 50to100 per carat. These stones may have pale color, visible inclusions, or poor cut.
- Medium-Quality Aquamarine: 100to300 per carat. These stones have good color, clarity, and cut but may not be exceptional.
- High-Quality Aquamarine: 300to500+ per carat. These stones have deep blue color, excellent clarity, and a well-proportioned cut.
- Exceptional Aquamarine: $1,000+ per carat. These stones are rare, with intense color, flawless clarity, and large carat weight.
It’s important to note that prices can fluctuate based on market demand, availability, and economic conditions. For example, if a new mine is discovered and produces a large quantity of high-quality aquamarine, prices may decrease temporarily. On the other hand, if a mine closes or production decreases, prices may rise.
