This 4.85 carat marjan is easy to check when it arrives. Use the points below, and ask us about anything you cannot judge from the photographs.

• Weight: 4.85 carats.
• Colour: a lighter red with an orange lean; view it by daylight, not only under indoor bulbs.
• Hardness: 3 to 4 on the Mohs scale, so handle it gently and look for marks on arrival.
• Treatment: waxing is frequent and some coral is dyed; ask us about AG-RC-0004.
• Surface: the polish should feel smooth and the red should look even, not patchy.

Around five carats is a size many ring makers work with: wide enough to show, still easy for daily wear in a bezel. Related stones are on the red coral page.

If the colour looks different once you hold it, tell us within the seven-day return period. Before you choose, read our red coral guide.

Cash on Delivery means you open the parcel first and pay second. Karachi deliveries usually take 1–2 working days, other cities 2–4.

This particular stone

This listing is one natural red coral, known in Urdu as Marjan, with a weight of 4.85 Carat. Its price is Rs. 6,530 — roughly Rs. 1,346 for each carat. Treatment: treatment not tested. Quote reference AG-RC-0004 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 red coral rates 3 to 4. That makes it soft for a gemstone, better suited to pendants, earrings and rings for special occasions than to a daily ring. Keep it away from perfume, cleaning products, steam and ultrasonic cleaners, and polish it with a dry, soft cloth after wear.

Whoever you buy red coral 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 red coral 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. No lab report yet; independent testing welcome.
