Guide to Buying Aquamarine Jewellery – 10 Facts

Are you thinking of buying aquamarine jewellery? Aquamarine is a sparkling and translucent gem with blue-green colour. The best aquamarines combine vivid blue-green colour with no visible markings inside the gem. Learn thow to buy the best aquamarine jewellery below.

Buying Aquamarine

1. Look for even blue-green colour

Colour is a vital factor in aquamarines. Aquamarine colour is typically light blue with a greenish or turquoise hue. Gem experts prefer aquamarines with even colour. In other words, you shouldn’t see lighter or darker colour patches within the gem.

2. Pick a clear gem

Most commercially sold aquamarines have no imperfections or markings (called inclusions) that you can see with an unaided eye. Unless you’re specifically buying a piece of jewellery where the main focus is an unpolished, rough aquamarine, then you should look for a clear, translucent gem.

3. Find a good cut

An aquamarine’s cut determines both its shape, and how much it sparkles. Therefore, an aquamarine that has good sparkle is usually well cut. Professional gem cutters love aquamarines because rough aquamarine can be cut into almost any shape. Having said that, oval cuts and rectangular emerald cuts are the most popular in jewellery.

4. Take advantage of carats and price

If you’re considering aquamarine jewellery, you should know that the larger the aquamarine you buy, the more value for money you’ll get. 

Why? As an example, let’s compare aquamarine to emeralds. As part of the beryl mineral family, aquamarine is related to the green emerald. But while emeralds crystals are small and hard to find without imperfections (making them expensive in large sizes), large aquamarine crystals are easy to find in eye-clear quality.

This means aquamarine gems won’t increase incrementally in per-carat value like other gems tend to. In other words, a 1.50-carat aquamarine will be worth roughly the same as a 0.30-carat gem of the same quality. Therefore it’s always worth considering a large piece if you can afford it.

6. Find out mining location

The finest aquamarine comes from Brazil. The Brazilian gem trade is largely artisanal and the government restricts mechanised mining to protect local tribes and the environment. Always make sure you choose ethical, conflict-free gems by purchasing aquamarine from jewellers who abide by the NAJ Code of Ethics.

7. Choose an aquamarine engagement ring with a robust setting

Aquamarine looks stunning in rings. However, it ranks 8 on the Mohs scale of mineral hardness, meaning that it is less durable than diamonds or sapphires. If you choose it as an engagement ring, it will be exposed to daily wear and tear for a lifetime. Therefore, make sure your aquamarine has a robust setting of gold or platinum to protect it from knocks and scratches.

8. Consider aquamarine as an alternative to diamonds

If you’re on a budget, aquamarine is a good alternative to diamonds. Firstly, these light blue gems offer breathtaking sparkle, like diamonds do. Secondly, they make very affordable jewellery pieces in large gem sizes so you can get an impressive piece of jewellery for your spend. Finally, their pale blue colour suits almost any complexion, in the same ways as diamonds do.

9. Always check returns policy and guarantee

You should always buy gemstone jewellery from a registered retailer that’s a member of the National Jewellers’ Association (NJA) to guarantee you’re buying the real thing. Also check the guarantee terms and return policy to cover your purchase.

10. Check measurements if ordering online

Don’t forget to check item measurements carefully when ordering aquamarine jewellery online. Do this with a ruler if necessary, to make sure the item is the size you hoped for and give you an idea of what it will look like when you wear it.
