Aquamarine makes a better ring stone than its reputation suggests. At 7.5 to 8 on the Mohs scale it is harder than quartz, agate or opal, and unlike emerald — its own close relative — it is usually free of the fractures that make a stone nervous to set. The things to get right are the setting and the size, and this page is about both.

The stone

31.50 carats, which is 34.62 ratti. Rs. 26,250, about Rs. 833 per carat, reference GS-000281. One piece, photographed as it is.

Specifying a ring for a stone this size

1. Open back, always. The single most useful instruction you can give. Aquamarine is pale; light entering from behind is what lifts the colour. A closed back makes it look grey.
2. Bezel over tall claws. Beryl is hard but it can chip on an edge. A rim of metal protects the girdle and keeps the profile low.
3. White metal. 925 silver, white gold or platinum keeps the blue clean and cool. Yellow gold warms it and draws out any green.
4. A broad shank. 8 to 11 mm for a stone of this weight, or the band will flex and eventually crack at the shoulders.
5. Measurements first. At over thirty carats a mount cannot be adapted afterwards.

Will it survive being worn?

For office wear, driving, prayer and ordinary handling, comfortably. Take it off for gym work, gardening and anything involving a hammer — most damage to a large ring happens to the setting rather than the stone. Clean it with warm soapy water and a soft brush. Avoid ultrasonic and steam cleaners; beryl can carry liquid inclusions that react badly to sudden heat.

Is 31.50 carats too big for a ring?

Not for the traditional style worn across Pakistan, which is built around stones of exactly this scale on a wide silver band. It will sit proud of the finger and it will be noticed — that is the point. If you want something lower-profile for daily wear, the aquamarine collection has stones under ten carats at a similar rate per carat.

Treatment

Aquamarine is commonly heated to remove green tones and leave a purer blue — standard for the gem, stable and accepted. We have not tested this stone, so the specification says "treatment not tested" rather than claiming it is unheated. A certificate of authenticity is available on request and independent laboratory testing can be arranged.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 31.5 Carat. Its price is Rs. 26,250 — roughly Rs. 833 for each carat. Treatment: treatment not tested. Quote reference GS-000281 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request.
