Ever gazed upon the mesmerizing blue-green hues of an aquamarine gemstone and wondered, “What makes this gem so enchanting, and how much is aquamarine worth?

We’re here to demystify the world of aquamarine, delving into its color, value, and worth, and providing you with all the information you need to make informed decisions when purchasing or evaluating aquamarine gemstones.

Understanding Aquamarine

What is Aquamarine?

Aquamarine is a semi-precious gemstone belonging to the beryl family, which also includes other popular gemstones such as emerald and morganite.

Its name originates from the Latin words “aqua” and “marina,” meaning “water” and “sea,” respectively—a fitting name for a gem that boasts colors reminiscent of the ocean.

Aquamarine Color

The aquamarine gemstone is known for its stunning blue-green color, which ranges from pale pastels to deep, vibrant hues. The color is derived from trace amounts of iron within the beryl crystal structure.

The most coveted aquamarine color is a rich, intense blue with a slight hint of green, often referred to as “Santa Maria blue” after the famous Santa Maria mines in Brazil.

Aquamarine Value Factors

When assessing the value of an aquamarine gemstone, four key factors come into play: color, clarity, cut, and carat weight.

  • Color

Color is the most crucial factor in determining an aquamarine’s value. The more saturated and intense the blue hue, the more valuable the gemstone. The best quality aquamarines exhibit a rich blue color with a hint of green, while lower quality stones may appear pale or washed out.

  • Clarity

Aquamarine is a relatively transparent gemstone, and it’s common for high-quality specimens to have few inclusions or blemishes. Stones with excellent clarity will be more valuable than those with visible inclusions or fractures.

  • Cut

The cut of an aquamarine can significantly impact its value, as it influences the stone’s ability to reflect light and display its color. A well-cut aquamarine will maximize its brilliance and color, while a poorly cut stone may appear dull or lifeless.

  • Carat Weight

As with most gemstones, larger aquamarines are generally more valuable than smaller ones. However, the value per carat doesn’t necessarily increase linearly with size, as it also depends on the gemstone’s color, clarity, and cut.

Aquamarine Pricing

Aquamarine prices can vary widely depending on the factors mentioned above. High-quality stones with intense blue color, excellent clarity, and a well-executed cut can fetch prices of several hundred dollars per carat.

However, more common stones with paler colors and visible inclusions may only be worth a few dollars per carat. It’s essential to consider all the value factors when determining an aquamarine’s worth.

Aquamarine Treatments and Enhancements

Aquamarines are often heat-treated to enhance their color and remove any greenish tints, resulting in a more desirable blue hue. This treatment is stable and typically accepted within the gemstone industry.

It’s crucial to ask about any treatments when purchasing an aquamarine, as treated stones may be worth less than their untreated counterparts.

Aquamarine vs. Other Gemstones

Aquamarine’s unique blue-green hue sets it apart from other blue gemstones, such as sapphires and topaz. Although it may not be as valuable or durable as sapphires, aquamarine’s serene color and clarity make it a popular choice for jewelry and collectors alike. When comparing aquamarine to other gemstones, consider factors such as color, durability, and personal preference.

How to Buy Aquamarine

  • Selecting the Right Aquamarine

When choosing an aquamarine gemstone, prioritize color, as it has the most significant impact on value. Opt for a stone with a rich blue hue and minimal green tints. Additionally, select a gem with excellent clarity and a well-executed cut that enhances the stone’s brilliance and color.

  • Choosing a Reputable Seller

Ensure that you purchase aquamarine from a reputable seller who provides detailed information about the gemstone, including any treatments or enhancements. A trustworthy seller will also offer a return policy or guarantee to protect your investment.

Caring for Aquamarine

Aquamarine has a hardness of 7.5 to 8 on the Mohs scale, making it a reasonably durable gemstone. However, it’s essential to protect your aquamarine from scratches and harsh chemicals.

Clean your aquamarine jewelry with a soft cloth and mild soap, and avoid exposing it to extreme temperatures or ultrasonic cleaners.

Aquamarine Symbolism and Uses

Throughout history, aquamarine has been associated with tranquility, protection, and good fortune. Sailors believed that the gemstone could calm stormy seas and protect them on their journeys.

Today, aquamarine is often used in meditation practices and is believed to promote inner peace and emotional balance.


Aquamarine’s captivating blue-green hue, combined with its exceptional clarity and symbolism, make it a highly sought-after gemstone. When evaluating an aquamarine’s worth, consider factors such as color, clarity, cut, carat weight, and any treatments or enhancements.

By selecting a high-quality stone and caring for it properly, you’ll be able to enjoy the beauty and serenity of aquamarine for years to come.
