Aquamarine VS Diamond: Which is More Expensive?

by Madonna

Gemstones have held a special place in human culture for millennia, prized for their beauty, rarity, and symbolism. Among the most coveted gemstones are diamonds and aquamarine, each with its unique allure and characteristics. In this article, we will explore the differences between diamonds and aquamarine in terms of rarity, quality factors, historical significance, market trends, and more, to determine which is more expensive and why.

Comparison of Rarity and Supply

Diamonds have long been regarded as one of the rarest and most valuable gemstones on Earth. Formed deep within the Earth’s mantle under extreme pressure and heat, diamonds are composed of carbon atoms arranged in a crystalline structure. While diamonds are found in various regions worldwide, including Africa, Australia, and Russia, only a small fraction of mined diamonds are of gem-quality, making them highly sought after.


Aquamarine, on the other hand, is a variety of the mineral beryl and is relatively more abundant compared to diamonds. It is found in various locations, including Brazil, Madagascar, and Nigeria. While aquamarine’s availability is greater than that of diamonds, high-quality specimens with intense color and clarity are still rare and command premium prices in the market.


In terms of rarity and supply, diamonds are generally scarcer than aquamarine, contributing to their higher price per carat.


Quality Factors

When assessing the value of diamonds and aquamarine, several quality factors come into play.

For diamonds, the famous “Four Cs” – cut, color, clarity, and carat weight – are used to determine their quality and value. A well-cut diamond maximizes its brilliance and sparkle, while colorless or near-colorless diamonds are considered more valuable. Clarity refers to the absence of internal flaws or inclusions, with flawless diamonds commanding the highest prices. Carat weight, referring to the size of the diamond, also influences its value, with larger diamonds typically fetching higher prices.

Similarly, aquamarine is evaluated based on color, clarity, cut, and carat weight. The most desirable aquamarines exhibit a vibrant blue hue with excellent clarity and transparency. Well-cut stones enhance the gem’s brilliance and color, while larger carat weights are rarer and thus more valuable.

Overall, both diamonds and aquamarine are assessed based on similar quality factors, with each gemstone possessing its unique characteristics that contribute to its value.

Color Comparison

Color is a crucial factor in determining the value of both diamonds and aquamarine.

In diamonds, color grades range from D (colorless) to Z (light yellow or brown), with colorless diamonds being the most valuable. However, colored diamonds, such as pink, blue, or yellow, known as fancy colored diamonds, can command even higher prices, depending on the intensity and rarity of the color.

Aquamarine derives its name from the Latin words “aqua” and “mare,” meaning water and sea, respectively, reflecting its beautiful blue-green hue reminiscent of the ocean. The most prized aquamarines exhibit a pure blue color with no hints of green or gray, resembling the clear waters of the Caribbean. Intense blue aquamarines are considered more valuable than lighter or greener varieties.

While both diamonds and aquamarine come in various colors, the rarity and desirability of certain hues can significantly affect their market value.

Historical Significance and Symbolism

Throughout history, diamonds have been revered for their exceptional hardness, brilliance, and enduring beauty. Ancient civilizations believed diamonds possessed mystical powers and associated them with strength, invincibility, and eternal love. Diamonds have been treasured by royalty and nobility for centuries, symbolizing wealth, status, and romance. Today, diamonds remain the ultimate symbol of love and commitment, adorning engagement rings and fine jewelry worldwide.

Aquamarine also boasts a rich historical significance and symbolism. In ancient folklore, aquamarine was believed to be the treasure of mermaids, offering protection to sailors and ensuring a safe voyage across the seas. The gemstone was also thought to enhance clarity of mind, promote inner peace, and bring harmony to relationships. Aquamarine has been cherished throughout history as a talisman of courage, hope, and good fortune, making it a popular choice for both personal adornment and spiritual healing.

While diamonds symbolize eternal love and prosperity, aquamarine embodies serenity, purity, and the boundless depths of the ocean, each carrying its unique historical significance and symbolism.

Famous Examples

Several famous diamonds and aquamarines have captivated the world with their extraordinary beauty and history.

The Hope Diamond, a legendary blue diamond weighing 45.52 carats, is one of the most famous diamonds in the world. With a rich history dating back centuries, the Hope Diamond is believed to be cursed, bringing misfortune to its owners. Today, it is housed in the Smithsonian Institution’s National Museum of Natural History, where it continues to mesmerize visitors with its deep blue hue and unparalleled brilliance.

In contrast, the Dom Pedro Aquamarine is a stunning example of the beauty and grandeur of aquamarine. Named after Brazil’s first two emperors, Dom Pedro I and Dom Pedro II, this remarkable gemstone weighs an astonishing 10,363 carats and is considered one of the largest and finest aquamarines ever discovered.
