At 26.2 carats, this Afghan aquamarine is priced at Rs. 11,250, about Rs. 429 per carat. A large aquamarine like this tends to cost less per carat than a small one, so the number tells you about size rather than weakness. Compare it with smaller pieces in the aquamarine range to see the pattern.

It is a natural aquamarine, beruj in Urdu, in sea blue from Afghanistan. Hardness is 7.5 to 8 on the Mohs scale. Because of the size, a pendant or a large statement ring are the sensible uses, and a protective bezel will keep the edges safe from knocks. A stone this big also shows its colour best when the setting is open at the back.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 26.2 Carat. Its price is Rs. 11,250 — roughly Rs. 429 for each carat. Origin: Afghanistan. Treatment: treatment not tested. Quote reference GS-000268 when you message us about it. The photographs show this exact stone, so what arrives at your door is the piece you chose on screen.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

On the Mohs scale aquamarine rates 7.5 to 8. It handles daily wear, but a hard knock can still nick an exposed corner, so a protective setting is a sensible choice. Clean it with warm soapy water and a soft brush, and keep it away from abrasive cleaners and high heat.

Whoever you buy aquamarine from, make sure of three things: the stone is natural rather than lab-grown, glass or glass-filled; any treatment is stated in writing; and the weight quoted is the weight of the finished stone. We check every aquamarine for those three points before it is listed, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
