Beruj is the name many Pakistani buyers use for aquamarine, and it is spoken of as a calm, watery blue stone, traditionally linked in the subcontinent with courage and clear speech. That is tradition and belief, and it adds to the stone's appeal without being a promise of any effect.

The hard facts

This is a natural aquamarine of 4.55 carats, a light blue beryl, priced at Rs. 9,000, or about Rs. 1,978 per carat. It rates 7.5 to 8 on the Mohs scale, which makes it suitable for rings as well as pendants.

Dealers routinely heat aquamarine to take out any greenish cast. Write to us on WhatsApp with reference GS-000265 and we will share what we know about this exact stone; independent lab testing is available on request.

A stone of this weight works well in a ring or a pendant, and the light blue shade is gentle enough to pair with both silver and yellow gold. A custom silver ring setting can be discussed on WhatsApp if you would like a bezel built around it.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 4.55 Carat. Its price is Rs. 9,000 — roughly Rs. 1,978 for each carat. Origin: Pakistan. Treatment: treatment not tested. Quote reference GS-000265 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.

Between two and six carats is the range most people choose for a gents' ring or a noticeable pendant. Here colour drives the price more than size does, which is why two stones of near-identical weight can be priced very differently.

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.
