Pros and Cons of Aquamarine Stones for Engagement Rings

What is Aquamarine?

Aquamarine is a blue to greenish-blue variety of beryl, a mineral that also includes other gemstones such as emerald and morganite. The name "aquamarine" is derived from the Latin words "aqua marina," which mean "sea water," a nod to its captivating sea-blue color that ranges from light to deep hues. This color is due to the presence of iron ions within the crystal structure of the stone.

Aquamarine is prized for its transparency and hardness, with a rating of 7.5 to 8 on the Mohs scale, making it quite durable and suitable for various types of jewelry, including rings, necklaces, and earrings. The most valued aquamarine stones have a deep blue color and are clear and free of inclusions, although the presence of natural inclusions can sometimes create interesting visual effects and increase the stone's uniqueness.

The stone is found in a variety of locations around the world, including Brazil, which is known for producing large and high-quality specimens. Other sources include Madagascar, Nigeria, Pakistan, Russia, and the United States, particularly in Colorado and North Carolina.

Aquamarine has been used for centuries, and it is believed to offer various metaphysical properties. It is associated with tranquility, serenity, clarity, and harmony. Historically, sailors wore aquamarine talismans to protect them at sea and ensure a safe voyage. In addition to its beauty and alleged protective qualities, aquamarine is also the birthstone for March and is often given as a gift for 19th wedding anniversaries.

Pros of Aquamarine Stones for Engagement Rings

Aquamarine, a gemstone beloved for its captivating sea-blue hues, has emerged as a popular choice for engagement rings, rivaling traditional diamonds. This gemstone, symbolizing tranquility, courage, and communication, offers a refreshing alternative with a host of advantages. Here's a detailed exploration of the pros of choosing aquamarine stones for engagement rings.

Unique Color and Aesthetic Appeal

Aquamarine, with its range from pale blue to deep sea-green, offers a unique color palette that stands out from the traditional diamond engagement ring. This gemstone's serene blue tones are associated with the tranquility of the ocean, making it an ideal symbol for a calm and harmonious marriage. Its unique aesthetic appeal caters to those looking for a distinctive piece of jewelry that reflects their personal style and the depth of their relationship.


One of the most significant advantages of aquamarine engagement rings is their affordability compared to diamonds. Aquamarines are more abundantly available and hence, more budget-friendly, allowing couples to opt for larger stones or more elaborate settings without stretching their finances. This affordability does not compromise the ring's beauty, making aquamarine an excellent choice for those who desire elegance and uniqueness on a budget.

Durability and Longevity

With a Mohs hardness rating of 7.5 to 8, aquamarines are durable enough for everyday wear. While not as hard as diamonds, they can withstand the rigors of daily life with proper care, making them a practical choice for engagement rings. Regular maintenance and precautions against hard impacts will ensure that the aquamarine retains its beauty for years to come.

Symbolic Meanings

Aquamarine is rich in symbolism, making it an ideal choice for couples looking to imbue their engagement ring with deeper meaning. Historically, sailors believed aquamarine to protect them at sea, symbolizing safety and security. In addition, it represents clarity, communication, and tranquility, qualities that are essential for a strong and lasting relationship. Choosing an aquamarine engagement ring can signify the couple's desire for a transparent, serene, and enduring union.

Variety and Flexibility in Design

Aquamarine's versatility in cut and clarity allows for a wide range of design possibilities, from classic to modern styles. Whether set in gold, silver, or platinum, and whether paired with other gemstones or standing alone, aquamarine can be tailored to fit any personal taste or preference. This flexibility enables couples to create a truly unique and personalized engagement ring.

Ethical and Sustainable Option

Aquamarines are often sourced in a more environmentally friendly and ethical manner compared to diamonds, which have been controversial due to issues such as conflict diamonds and the environmental impact of mining. For couples concerned with the ethical implications of their jewelry choices, aquamarine offers a more sustainable and conflict-free alternative.

Light-Reflecting Properties

Aquamarine's ability to reflect light beautifully, especially in well-cut specimens, adds to its appeal as a choice for engagement rings. Its brilliance and sparkle, although different from a diamond's, can capture the eye and make a statement. The light-reflecting properties of aquamarine, combined with its unique color, create a captivating visual effect that is both elegant and striking.

Cons of Aquamarine Stones for Engagement Rings

While aquamarine stones offer a captivating choice for engagement rings with their unique hue and symbolic significance, it's essential to consider their drawbacks. These cons may affect a couple's decision when selecting the ideal stone for their engagement ring. Here's a detailed exploration of the potential downsides of choosing aquamarine stones for engagement rings.

Relative Softness and Durability

Although aquamarines have a decent hardness rating of 7.5 to 8 on the Mohs scale, they are softer compared to diamonds, which score a perfect 10. This relative softness means aquamarines are more susceptible to scratches and abrasions over time, especially with daily wear. To maintain their beauty, aquamarine rings may require more frequent care and precautions against rough handling, which could be a significant consideration for those with active lifestyles.

Sensitivity to Chemicals and Heat

Aquamarines can be sensitive to harsh chemicals and extreme heat. Exposure to household chemicals, such as chlorine and abrasives, can damage the surface of the stone or alter its color. Similarly, high temperatures can cause an aquamarine to crack or lose its color. This sensitivity necessitates careful handling and maintenance, potentially limiting the practicality of aquamarine as an everyday piece of jewelry.

Color Fading

One of the defining features of aquamarine—their vibrant color—can also be a vulnerability. Over time, prolonged exposure to sunlight can cause the color of aquamarine to fade, diminishing its stunning blue or blue-green hue. This aspect means that an aquamarine engagement ring may lose some of its initial allure with years of wear, particularly if not properly cared for.

Limited Brilliance Compared to Diamonds

While aquamarines can exhibit a lovely sparkle, their brilliance and fire are generally less intense than that of diamonds. The refractive index of aquamarine is lower than that of diamonds, meaning it doesn't disperse light as effectively to create the same sparkling effect. For those who prioritize the sparkle and brilliance commonly associated with engagement rings, aquamarine might not meet their expectations.

Rarity of High-Quality Stones

Although aquamarines are more abundant and affordable than diamonds, finding high-quality aquamarines—those with deep, vivid colors and high clarity—can be challenging and often more expensive. The most desirable shades of deep blue or blue-green are rare, driving up the price for these premium stones. This rarity may limit options for couples seeking the most vibrant and flawless aquamarines for their engagement rings.

Ethical and Environmental Concerns

While aquamarines are often marketed as more ethical and sustainable than diamonds, mining for aquamarines still poses environmental and ethical concerns. The mining process can lead to habitat destruction, water pollution, and other environmental impacts. Furthermore, not all aquamarine mines operate under ethical labor practices. Prospective buyers should research the source of their aquamarine to ensure it aligns with their values.

Perceived Value and Tradition

In many cultures, diamonds are traditionally associated with engagement rings, symbolizing durability and eternal love. Opting for an aquamarine stone might not resonate with everyone, especially those who value tradition or perceive diamonds as a status symbol. The choice of aquamarine over diamond could be viewed by some as less prestigious or valuable, potentially impacting the sentimental value placed on the ring.


While aquamarine engagement rings offer a unique and meaningful choice, it's important to weigh these potential drawbacks. The stone's softer nature, care requirements, and the rarity of high-quality specimens can pose challenges. Additionally, considerations around brilliance, color stability, ethical sourcing, and traditional values may influence a couple's decision. Understanding these cons will help ensure that the choice of an aquamarine engagement ring aligns with the wearer's lifestyle, values, and aesthetic preferences, ensuring that the symbol of their commitment stands the test of time.
