"High quality" is easy to type and hard to prove, so here is the checklist that actually separates a good aquamarine from an ordinary one — and where this stone stands against it. Note first that the rate, about Rs. 1,651 per carat, is near the top of our range in a gem where weight carries no premium. That gap is paid for by quality alone.

The stone

5.45 carats, which is 5.99 ratti. Blue Beruj. Rs. 9,000, about Rs. 1,651 per carat, reference GS-000271. One piece only.

The five things that matter, in order

1. Clarity. Fine aquamarine is expected to be eye-clean. This is where most of the price difference in our collection comes from — our included stones sit under Rs. 400 a carat.
2. Colour that holds up. A blue that stays visible under ordinary indoor light, rather than only looking good at a window.
3. Cut, and specifically brightness. In a pale gem the cut does the work colour cannot. A bright, busy face beats a flat one every time.
4. No window. Hold it over printed text. If you can read through the middle of the table, light is leaking out of the back.
5. Orientation. Beryl is pleochroic — the colour differs along different crystal directions — so a cutter who orients the rough well gets a better blue from the same material. Invisible craft you pay for without seeing it.

What we have not verified

Part of the same argument. Shape, measurements and clarity grade are not recorded for this piece, and those fields stay blank rather than being filled with plausible guesses. Treatment has not been tested either — aquamarine is commonly heated to remove green tones and leave a purer blue, and we will not claim a stone is unheated without a report. Ask us on WhatsApp at +92 308 887 3888 and we will measure it, photograph it against a scale, or send it for independent laboratory testing.

Is it worth paying more per carat?

Only if you can see the difference. Open this listing and one of our large included stones side by side in two browser tabs and compare the photographs at full size — they are not colour-corrected. If the clarity and the blue do not look better to you, buy the cheaper stone. We would rather sell you the right one than the dearer one.

Does high quality mean certified?

No — separate claims. A certificate of authenticity is available on request and independent laboratory testing can be arranged, but no certificate grades beauty.

Setting

Open back and white metal, both of which lift a pale blue. A low bezel protects the edge; beryl is hard at 7.5 to 8 on the Mohs scale but can chip on a sharp knock.

Ordering

One piece only. Flat Rs. 500 delivery anywhere in Pakistan, insured and tracked, dispatched in one to two working days. Cash on Delivery, seven days to return it unused. Compare the range in the beruj collection.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 5.45 Carat. Its price is Rs. 9,000 — roughly Rs. 1,651 for each carat. Treatment: treatment not tested. Quote reference GS-000271 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request. As general background (not a statement about this stone): Aquamarine is commonly heated to remove green tones and leave a purer blue. Ask us on WhatsApp and we will tell you what we know about this exact stone; independent lab testing is available on request.

A certificate of authenticity is available on request for this stone, and independent laboratory testing can be arranged. Because you pay on delivery, you can also take the stone to a lab of your choice within the 7-day return window. Read more on our authenticity page.
