Preserving Brilliance: The Truth About Aquamarine and Sunlight

by Madonna

The allure of aquamarine, with its soothing blue hues reminiscent of tranquil waters, has captivated jewelry enthusiasts and collectors for generations. Yet, like any precious gemstone, aquamarine warrants careful consideration when it comes to its care and maintenance. A common question that arises is: Does aquamarine fade in sunlight? In this comprehensive exploration, we uncover the truth behind the relationship between aquamarine and sunlight, providing valuable insights for those who cherish this gemstone’s beauty.

History of Aquamarine

The history of aquamarine dates back to ancient times. The gem’s name is derived from the Latin words “aqua” (water) and “mare” (sea), reflecting its ocean-like color. It was believed to be a talisman for sailors, protecting them during sea voyages. In ancient Egypt and Rome, aquamarine was associated with water deities and used as a symbol of purity and protection. Throughout history, aquamarine was cherished for its calming and soothing properties. It gained prominence in jewelry during the Art Deco period. Today, aquamarine remains a beloved gemstone, symbolizing serenity, communication, and inner strength.

How Aquamarine Is Formed?

Aquamarine forms through hydrothermal processes. Hot water rich in minerals, including beryllium, aluminum, and silicon, infiltrates existing rock cavities. As the solution cools, beryl crystals begin to grow. Iron impurities within the crystal structure lend aquamarine its characteristic blue-green color. The process can take millions of years. Gem-quality aquamarine often occurs in pegmatite veins, where the larger crystals form. Geological conditions, including pressure and temperature, influence the crystal’s growth, resulting in the beautiful blue and blue-green hues. Once formed, aquamarine can be found in deposits around the world, often associated with granitic rocks and pegmatites.


Aquamarine’s Delicate Dance with Light

Before diving into the question of whether aquamarine fades in sunlight, it’s essential to understand the gemstone’s interaction with light. Aquamarine, a variety of beryl, derives its captivating blue or blue-green color from the presence of iron ions within its crystal lattice. These iron ions absorb certain wavelengths of light, resulting in the gemstone’s characteristic coloration. The interplay between light and the gemstone’s internal structure is what allows aquamarine to showcase its captivating brilliance and luster.

How Gemstones Respond to Sunlight?

Sunlight, while a source of warmth and life, can have varying effects on different gemstones. For aquamarine, exposure to sunlight is generally safe and does not result in fading or significant damage. However, it’s important to consider certain factors that may influence the gemstone’s response to sunlight:

1. Intensity and Duration:

Prolonged and intense exposure to direct sunlight can potentially affect the color of aquamarine over an extended period. While short periods of exposure, such as wearing aquamarine jewelry outside, are unlikely to cause fading, it’s advisable to limit prolonged exposure to maintain the gemstone’s vibrancy.

2. Artificial Lighting:

While sunlight is a consideration, exposure to artificial lighting sources, such as ultraviolet (UV) lights commonly found in tanning beds or some indoor lighting fixtures, can potentially cause damage over time. UV radiation can impact the gemstone’s color and structural integrity, leading to fading and weakening of the crystal lattice.

3. Heat:

Intense heat, often associated with direct sunlight, can potentially impact the gemstone’s internal structure and color. However, aquamarine is relatively heat-resistant and requires significantly high temperatures to cause noticeable damage.

What is the price of aquamarine?

The price of aquamarine varies widely based on factors like color, clarity, size, and origin. Commercial-grade aquamarines can start from around $10 to $50 per carat. However, high-quality, vivid blue or blue-green aquamarines with minimal inclusions can range from $100 to $1,000 or more per carat. Larger stones, exceptional color, and notable origins like Santa Maria in Brazil or Madagascar can command premium prices. Fine-quality aquamarines with vivid hues and minimal inclusions are more valuable. It’s important to consider certifications, consult reputable sources, and assess the gem’s attributes to determine its value accurately.

Caring for Aquamarine: Best Practices

To ensure the lasting beauty and brilliance of your aquamarine jewelry, following proper care practices is essential. Here are some guidelines to consider:

1. Avoid Prolonged Sun Exposure:

While aquamarine is generally resilient to sunlight, it’s advisable to minimize prolonged exposure to intense sunlight, especially if your jewelry features delicate settings or includes other gemstones that might be more sensitive to UV radiation.

2. Storage:

When not wearing your aquamarine jewelry, store it in a fabric-lined jewelry box or pouch to protect it from light, dust, and potential scratches. This practice helps preserve its luster and minimize the risk of exposure to harsh conditions.

3. Cleaning:

To maintain the gemstone’s brilliance, clean your aquamarine jewelry regularly using mild soap and lukewarm water. Gently scrub the gemstone with a soft brush or cloth, and then rinse and dry it thoroughly.

4. Professional Inspection:

Periodically have your aquamarine jewelry inspected by a professional jeweler. They can assess the gemstone’s condition, settings, and overall integrity, ensuring that any potential issues are addressed promptly.

Myths and Misconceptions: Separating Fact from Fiction

The world of gemstones often carries with it a host of myths and misconceptions. When it comes to aquamarine and sunlight, separating fact from fiction is crucial. Here are a couple of common misconceptions to consider:

Myth 1: Aquamarine Fades Quickly in Sunlight:

This myth tends to exaggerate the effects of sunlight on aquamarine. While prolonged exposure to intense sunlight can potentially impact the gemstone’s color over an extended period, the fading process is gradual and not immediate.

Myth 2: All Gemstones React the Same Way to Sunlight:

Different gemstones have varying responses to sunlight and UV radiation. While some gemstones are sensitive to light and may fade or change color rapidly, others, like aquamarine, are relatively resilient and require prolonged exposure to noticeable changes.


In the realm of gemstones, aquamarine’s beauty and resilience shine bright. While concerns about fading due to sunlight are valid, the effects are generally minimal when compared to more light-sensitive gemstones. As long as aquamarine jewelry is treated with care and thoughtfulness, its brilliance and color can be enjoyed for years to come.

Ultimately, responsible care practices extend the longevity of your aquamarine jewelry. Limiting prolonged exposure to intense sunlight, storing your pieces appropriately, and adhering to recommended cleaning routines can help ensure that your aquamarine jewelry remains as captivating as the day you acquired it. The enduring allure of aquamarine, like the tranquil waters it mirrors, continues to grace the world of jewelry with its calming elegance, a beauty that remains unwavering even under the gentle touch of sunlight.
