Coral started life as the hard skeleton of tiny sea animals, and this 3.8 carat marjan still carries the gentle character that comes with that history. Its colour is a warm, even red, neither pale nor very dark, a comfortable middle tone. The reference is AG-RC-0003.

That organic origin also makes coral soft, 3 to 4 on the Mohs scale, well below sapphire or even quartz. A protective bezel setting is wise, and perfume, chlorine and harsh cleaners are best kept away. A slim silver band or ladies' ring suits this weight nicely.

Coral is often waxed for shine, and some is dyed; that is simply how the trade works. Ask us about this particular piece and we will tell you what we know.

When the parcel is opened, look for a smooth, even surface and a steady colour from edge to edge. Those are the signs that matter most in coral.

The red coral listings show other marjan, and our rashi guide covers the astrology side for those who follow it.

All orders are Cash on Delivery: open, inspect, then pay. Karachi usually has it within 1–2 working days, the rest of Pakistan within 2–4, and you can return it unused within 7 days.

This particular stone

This listing is one natural red coral, known in Urdu as Marjan, with a weight of 3.8 Carat. Its price is Rs. 5,700 — roughly Rs. 1,500 for each carat. Treatment: treatment not tested. Quote reference AG-RC-0003 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.
