Sea blue like this makes people ask how it was done, and the answer is that beryl takes up the colour naturally. This 33.2 carat aquamarine comes from Afghanistan, a source Pakistani gem markets know well, and it is one of the bigger pieces we have.

It is a natural beruj, 7.5 to 8 on the Mohs scale, and its reference is AG-000258. At this weight it is bold enough for a pendant or a wide ring, and it sits among the larger stones in our aquamarine range.

Heat is the question to put to any seller. Aquamarine is commonly heated to strip out greenish tones and leave a purer blue, and the trade treats this as ordinary. Ask us about this stone and we will tell you what we know; an independent lab test is your choice.

Being hard, it handles daily wear better than softer gems, but a sharp knock on an exposed edge can still damage it. It ships Cash on Delivery, so you can open the parcel and inspect the stone before you pay.

Karachi usually receives it in 1–2 working days, other cities in 2–4, and returns are accepted for 7 days. Read our aquamarine guide before choosing.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 33.2 Carat. Its price is Rs. 18,750 — roughly Rs. 565 for each carat. Origin: Afghanistan. Treatment: treatment not tested. Quote reference AG-000258 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, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
