The allure of aquamarine gemstones lies in their captivating blue hues that evoke images of tranquil waters and serene skies. However, it can be perplexing and disappointing when an aquamarine gemstone doesn’t exhibit the expected blue color. Variations in color within the aquamarine family are not uncommon and can be attributed to a range of factors. In this article, we unravel the mystery behind aquamarines that aren’t blue, exploring the reasons behind their color diversity and the unique beauty they possess.
Which mineral family does aquamarine belong?
Aquamarine belongs to the mineral family of beryl. Beryl is a mineral composed of beryllium aluminum cyclosilicate, and it forms in various colors due to the presence of different trace elements. Aquamarine is a variety of beryl known for its beautiful blue to bluish-green color, which is caused by the presence of iron impurities. Other well-known varieties of beryl include emerald (green), morganite (pink to peach), and heliodor (yellow). Beryl is valued for its clarity, hardness, and range of colors, making it a popular choice for gemstone jewelry and mineral specimens.
What Hue is Aquamarine?
Aquamarine exhibits a captivating blue to bluish-green hue, reminiscent of the clear waters of the sea. The color of aquamarine ranges from pale, almost transparent, shades of blue to deeper, more intense blues with hints of green. The presence of iron in the crystal structure contributes to its distinctive coloration. The name “aquamarine” is derived from the Latin words “aqua” (water) and “mare” (sea), perfectly encapsulating the gemstone’s serene and soothing color that evokes the tranquility of ocean waters. This appealing range of hues makes aquamarine a popular choice for jewelry and decorative pieces, symbolizing clarity and calmness.
Does Aquamarine Have a Green Tint?
Aquamarine can have a green tint, but the intensity of the green varies. Aquamarine is known for its blue to bluish-green color range, with some stones leaning more toward blue while others have a stronger greenish hue. The presence of iron impurities within the crystal structure influences the coloration. Lighter aquamarines may display a subtle greenish undertone, while deeper-toned stones can exhibit a more noticeable bluish-green or teal color. The green tint adds to the gemstone’s charm, reminiscent of the shades found in ocean waters. The variation in color makes each aquamarine unique, appealing to different tastes and preferences.
What are the reasons why aquamarine is not blue?
Aquamarine is indeed known for its blue to bluish-green color range. However, the reasons why some aquamarines might not appear as blue as expected could be due to a combination of factors:
1. Iron Content:
The presence of iron impurities within the crystal structure of aquamarine is responsible for its color. The varying amounts of iron and how it interacts with other elements can result in different shades, ranging from blue to bluish-green.
2. Trace Elements:
Apart from iron, other trace elements can also influence the color. For example, the presence of chromium might contribute to a more greenish tint in some aquamarines.
3. Geological Conditions:
The color of aquamarine is influenced by the specific geological conditions under which it forms. Variations in temperature, pressure, and mineral composition during formation can affect the gemstone’s color.
4. Heat Treatment:
Sometimes, heat treatment can be applied to enhance the color of aquamarine. This can result in a bluer appearance or intensify the existing blue.
5. Quality and Origin:
The quality of aquamarine can vary based on its origin. Some regions might produce aquamarines with different color tendencies due to unique geological factors.
It’s important to note that aquamarine’s color variation is part of its natural beauty. Different shades and tints add to its uniqueness and appeal, offering a range of options for those who appreciate its serene and calming color palette.

Heat Treatment of Aquamarine
Heat treatment is a common practice in the gemstone industry, including for aquamarine. Aquamarines are sometimes subjected to controlled heat to enhance their color and clarity. The heat treatment process involves heating the gemstones to specific temperatures, which can cause the iron and other trace elements responsible for color to realign and improve the overall color saturation. This treatment can intensify the blue hues and remove any unwanted greenish tints, resulting in a more desirable and consistent color. Heat-treated aquamarines are widely accepted in the market, but disclosure of any treatment is important to maintain transparency and informed consumer choices.
