Every stone on this site is sold loose, which means unset: the gem on its own, with no ring, no pendant and no mount. For a small accent stone like this one that is almost always the right way to buy, and it is worth explaining why rather than assuming you already know.

The stone

2.30 carats, which is 2.53 ratti. Rs. 4,500, about Rs. 1,957 per carat, reference GS-000270. One piece only.

Why buy loose

• You can see the whole stone. Nothing is hidden under a bezel or behind claws. Inclusions and cutting faults have nowhere to go.
• The two prices stay separate. You know what the gem cost and what the metalwork cost. In finished jewellery those are rolled into one figure and the split is rarely in your favour.
• The design is yours. Your jeweller builds around the stone instead of you picking from whatever stock mounts happen to exist.
• It posts and returns easily. A loose stone is simple to inspect on delivery and simple to send back.

What a 2.30 carat aquamarine is for

This is accent-stone territory rather than a centrepiece: a side stone, a small pendant, a ring for a slim finger, or a pair if you can match it. Be realistic about colour at this size — aquamarine is a pale gem, and the less depth light travels through, the lighter it reads. A two carat stone will look noticeably paler than a twenty carat one cut from the same crystal. That is physics, not quality. If you want presence, the larger stones in the aquamarine collection cost far less per carat.

Why is the per-carat rate so high on a small stone?

Because the fixed cost of cutting is spread over fewer carats, and because beryl carries no scarcity premium for size. Small stones in this gem are simply dearer per carat than large ones — the opposite of sapphire. Our price guide sets it out.

What to do when it arrives

Look at it in daylight and under room light. Check the table for a window by holding it over printed text. Then take it to your jeweller with a clear idea of the piece you want. You pay the rider only after the parcel is open, and the seven-day return window runs from delivery.

Treatment and verification

Aquamarine is commonly heated to remove green tones and leave a purer blue — standard and stable. We have not tested this stone, so the specification says so. A certificate of authenticity is available on request and independent laboratory testing can be arranged. More on the authenticity page.

Durability

Beryl is 7.5 to 8 on the Mohs scale. Warm soapy water and a soft brush; avoid steam and ultrasonic cleaners.

This particular stone

This listing is one natural aquamarine, known in Urdu as Beruj, with a weight of 2.3 Carat. Its price is Rs. 4,500 — roughly Rs. 1,957 for each carat. Treatment: treatment not tested. Quote reference GS-000270 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.
