Aquamarine Gemstone Guide: Meaning, Value, Colour & Buying Tips

The aquamarine gemstone is loved for its serene blue tones, timeless elegance and rich history. 

Often associated with clarity and calm, aquamarine has become a popular choice for fine jewellery, engagement rings and meaningful gifts.

If you’re exploring what kind of gemstone is aquamarine, its symbolism, properties and market value, this comprehensive guide will help you understand exactly what makes this sea-blue stone so desirable. 

Let’s dive into aquamarine.

First of all, what is the aquamarine?

In other words, is aquamarine a gemstone? Absolutely. 

The aquamarine gemstone is a member of the beryl family, the same mineral group that includes emerald. Its name comes from the Latin words aqua (water) and marina (sea), reflecting its ocean-like colour.

Other names for this gem are rare, as the stone is widely recognised under its traditional name. It has been treasured for centuries and is especially admired for its transparency and luminous glow.

Aquamarine gemstone meaning & symbolism

The aquamarine’s meaning is strongly connected to calmness and emotional balance. 

Historically, sailors carried aquamarine as a protective talisman, believing it would ensure safe voyages across turbulent seas.

Today, aquamarine gemstone meaning is often associated with:

  • Tranquillity and peace
  • Clear communication
  • Emotional clarity
  • Courage during change

Because of its soothing appearance, many people also explore the perceived healing properties of the aquamarine gemstone. 

While these beliefs are symbolic rather than scientific, aquamarine is commonly linked to stress relief and mental clarity.

Aquamarine colour: shades & variations

One of the most important characteristics of the aquamarine gemstone is its colour. But what colour is an aquamarine gemstone exactly?

Its colours range from very pale sky blue to deeper blue-green tones. The most valuable stones typically display a pure, medium blue shade without grey undertones.

Common shades of the aquamarine gemstone include:

  • Pale icy blue
  • Light ocean blue
  • Blue-green seafoam
  • Medium vibrant blue

Saturation and clarity directly impact an aquamarine’s value. The deeper and more vivid the blue (without becoming dark), the higher the demand.

Aquamarine gemstone properties & hardness

Understanding aquamarine gemstone’s properties is essential before buying. Here is all you need to know about its core properties:

  • Mineral family: Beryl
  • Chemical composition: Beryllium aluminium silicate
  • Crystal system: Hexagonal
  • Transparency: Typically transparent
  • Lustre: Vitreous

When it comes to durability, aquamarine gemstone’s hardness measures 7.5 to 8 on the Mohs hardness scale. This makes aquamarine a relatively hard gemstone, suitable for rings and everyday jewellery, though it should still be handled with care.

Because of its clarity and structure, aquamarine is often cut into oval, emerald, round and cushion shapes to maximise brilliance.

Aquamarine facts & history

This gemstone’s history dates back to ancient civilisations. Romans believed it absorbed the spirit of the sea, while medieval healers considered it a stone of foresight and protection.

Some notable aquamarine facts:

  • Large crystals are more common than with many other precious stones.
  • It is often eye-clean, meaning inclusions are minimal to the naked eye.
  • It is sometimes gently heat-treated to enhance its blue tone, a standard and accepted practice in the gemstone industry.

Aquamarine gemstone cost & market value

One of the most common questions we get is: what determines an aquamarine gemstone’s cost?

Well, there are several factors that influence the aquamarine’s value and they need to be taken into account in combination:

  1. Colour intensity - Stronger blue tones increase price.
  2. Clarity - High transparency with minimal inclusions is preferred.
  3. Carat weight - Larger stones command higher prices per carat.
  4. Cut quality - Proper proportions enhance brilliance.

The gemstone price per carat can vary widely. Lighter stones may start from a few hundred A$ per carat, while fine-quality, deeper blue stones can reach significantly higher figures depending on size and origin.

Unlike diamonds, aquamarine pricing is less standardised, so evaluating colour and clarity by a trusted jeweller is even more crucial.
