Aquamarine - March Birthstone

Happy Birthday, Aqua!

Did you know that although aquamarine has been popular for many years, there was a sudden spike in interest and popularity after Meghan Markle wore an aquamarine cocktail ring after her wedding to Prince Harry in May 2018.

This gorgeous piece once belonged to his mother, Princess Diana, along with a matching bracelet.

Let's take a closer look at this wonderful gem.

Let's begin with some fun facts:

  • Aquamarine is a part of the beryl family (along with Emerald and Morganite)

  • Its colour ranges from blue to greenish blue

  • Aquamarine is derived from two Latin words: aqua meaning "water" and marina meaning "of the sea"

  • Most of the aquamarine on the market is light blue

  • Deeper blue colours (as pictured above) are typically more expensive

  • Almost all aquamarine on the market is eye-clean (no noticeable inclusions)

  • Aquamarine can be confused with a much less expensive stone, Blue Topaz

  • Aquamarine crystal structure is elongated, which is why it is typically cut into elongated shapes, such as emerald cuts, ovals and elongated cushions

Brazil has been the world's most important source of aquamarine since 1811, with most mines located in the northeast Minas Gerais. This is where Princess Diana's aquamarine was sourced, along with other aquas in Queen Elizabeth II's collection.

Other, newer sources include Nigeria, Madagascar, Mozambique and Pakistan.

Aquamarine forms in large crystals, with some specimens reportedly weighing up to 100 lbs. Consequently, it is available in a large variety of shapes and sizes making it perfect for large statement pieces such as cocktail rings as well as smaller jewellery items.

But don’t go too small, the smaller the stone, the lighter the colour looks.

Larger stones show more saturated colour. This is also the case for another stone from the beryl family - Morganite

Aquamarine Treatments

Aquamarine is heat treated in order to remove the unwanted yellow and brown colour and leave a purer blue hue. Due to the lack of inclusions in aqua, heat treatment is undetectable and the colour is permanent.

In order for the gem to receive an Aquamarine name, it must have a blue hue.

Untreated beryl which does not show a strong enough blue colour is sometimes sold as green beryl (below).

In terms of hardness, aquamarine scores a 7.5 - 8 out of 10 on Moh's scale.

With sapphires and rubies at 9 and diamonds at 10, these can scratch your aqua if not stored properly or if they rub against each other.
