Aquamarine is a gorgeous blue-green gemstone that has been cherished by humans for centuries. Its beauty and durability make it an ideal choice for jewelry and decorative items.
In this blog post, we will delve into the history, properties, and uses of aquamarine. We’ll also explore how to identify and care for jewelry, famous aquamarine gemstones, its representation in popular culture, and what it symbolizes.
What is Aquamarine?
Aquamarine is a member of the beryl family, which includes other well-known gemstones like emeralds and morganite. Its name comes from the Latin words “aqua” meaning water and “marina” meaning sea, which accurately describes its breathtaking blue-green hue.
Aquamarine is considered a semi-precious stone, although high-quality specimens can command a premium price. Its hardness on the Mohs scale is 7.5-8, making it a durable gemstone for everyday wear.
Aquamarine typically forms in granite rocks or pegmatites that were exposed to hydrothermal activity. This process involves hot fluids circulating through the rock, dissolving minerals, and then depositing them in cracks and crevices.
The specific chemical composition of these fluids determines the color of the aquamarine. Iron ions give it its blue-green color, while the presence of more manganese gives rise to pink hues.
The Colors of Aquamarine
While aquamarine’s primary color is blue-green, there are variations in hue depending on the concentration of iron ions and other trace elements present. Some gemstones may exhibit a greenish-yellow hue, while others may have a bluish-gray tint.
Gemstones with no visible inclusions and a deep blue color are considered the most valuable and sought-after.
Properties of Aquamarine
Aquamarine has several unique properties that make it a popular choice for jewelry and decorative items. These include its hardness, clarity, and refractive index.
Hardness
Aquamarine has a hardness of 7.5-8 on the Mohs scale, making it durable enough for everyday wear. However, it’s still important to take care when wearing and cleaning jewelry.
Clarity
Aquamarine is a relatively clear gemstone with no visible inclusions. This clarity allows for maximum light transmission, giving it a brilliant sparkle.
Refractive Index
Aquamarine has a refractive index of 1.577-1.583, which measures how much light bends as it passes through the gemstone. This property is important in determining the stone’s brilliance and fire.
How to Identify Aquamarine
Identifying it can be challenging, as it can look very similar to other stones like blue topaz or blue zircon. Here are some tips to help you identify aquamarine:
- Color: it’s primary color is blue-green, but it may have variations depending on the concentration of trace elements present.
- Hardness: it has a hardness of 7.5-8 on the Mohs scale, which makes it harder than most other gemstones with a similar appearance.

Additional Testing
If you’re still unsure whether a stone is aquamarine, there are additional tests you can perform. For example, it has a specific gravity of 2.68-2.74, meaning it’s denser than most other blue stones like blue topaz or blue zircon. You can also test the stone’s reaction to UV light or test its thermal conductivity to help confirm its identity.
