What Is Aquamarine?
The name aquamarine comes from the Latin aqua marina, meaning “water of the sea”, a nod to its clear blue colour that calls to mind calm coastal waters. Aquamarine is a blue to blue-green variety of the mineral beryl, the same family as emerald and morganite. Chemically, beryl is a beryllium aluminium cyclosilicate with the formula Be3Al2Si6O18. Gentle heat treatment is commonly used to deepen its blue tone. On the Mohs hardness scale, aquamarine typically ranges from 7.5 to 8, making it suitable for everyday jewellery with sensible care.
Significant sources include Brazil and Colombia in South America, Kenya, Tanzania and Malawi in Africa, as well as the state of Wyoming in the USA.

How to Choose a Quality Aquamarine

- Clarity: Aquamarine is often eye-clean. Minimal visible inclusions will keep the gem bright and lively.
- Cut: A well-executed cut enhances brilliance and colour. Popular shapes include emerald cut, oval and cushion.
- Size: Beryl often forms large crystals, so attractive, larger stones are available without being extremely rare.
- Setting: Choose protective settings for rings if you lead an active lifestyle, given everyday knocks.
Caring for Your Aquamarine Jewellery
- Clean gently with warm water, mild soap and a soft brush. Rinse and dry thoroughly.
- Avoid harsh chemicals and extreme heat. Store separately to prevent scratching softer gems.
