Five carats exactly, cut as an oval, with the colour recorded as Red. Both of those are on the record for this stone rather than read off a photograph: the shape is recorded as oval in our stone file, and the photograph agrees with it.

Why an oval, and what it does

The oval is the most common shape in coloured stones for a reason. It keeps more of the original rough than a circular cut does, so you pay for less waste, and it spreads the stone slightly along the finger, which makes a given weight look larger than it would if it were cut as a circle. It also takes brilliant-style faceting well, so the stone works light rather than just showing colour.

The numbers

The price is Rs. 40,500, which is about Rs. 8,100 per carat. In ratti, 5.00 carats is 5.49 ratti. The reference is GS-000548. A clean five-carat figure is unusually convenient if you are comparing against a jeweller's quote, so it is worth doing that comparison on this one.

Ruby, yaqoot and hardness

Ruby is red corundum, yaqoot in Urdu, at 9 on the Mohs scale. For a stone you intend to wear rather than keep in a box, that number is the single most useful fact on this page. It is why a ruby ring still looks right after ten years while softer stones in the same drawer have gone cloudy at the edges.

Treatment, and what we have not done

Most ruby (yaqoot) is heated, and lower grades may be glass-filled; we do not sell glass-filled ruby as natural ruby. This stone has not been tested, and there is no laboratory report for it. We will not call it unheated when no one has looked, and we will not promise you a document that does not exist. Independent testing can be arranged before you commit.

Setting and care

Five carats suits a gents ring or a pendant that is meant to be noticed. Claws let light in at the sides and suit this shape; a bezel is tougher. Warm water, mild soap, soft brush. No ultrasonic, no steam.

Questions people ask about this stone

Is the oval shape recorded or guessed? Recorded. It is in our stone file for this piece, and the photograph agrees with it. Most of the shape claims that were on these pages before this rewrite were neither.

Why does it cost so much more than the other five carat ruby here? Colour. This one's record reads Red and the other reads Pinkish red. Same weight, same mineral, very different material, and the rate follows the material.

Is Rs. 40,500 negotiable? Ask us on WhatsApp with GS-000548. What we will not do is move the price by quietly changing what the stone is said to be.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 5 Carat. Its price is Rs. 40,500 — roughly Rs. 8,100 for each carat. Treatment: treatment not tested. Quote reference GS-000548 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 ruby rates 9. Few materials will scratch it, so it copes well with everyday ring wear. A soak in warm water with a drop of mild soap and a soft brush keeps it bright; skip the ultrasonic cleaner if inclusions reach the surface.

Whoever you buy ruby 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 ruby 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): Most ruby (yaqoot) is heated, and lower grades may be glass-filled; we do not sell glass-filled ruby as natural ruby. 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.
