Coral is soft. At 3 to 4 on the Mohs scale it will scratch against a key ring, and acids can etch it, so a ring set with this 5.95 carat marjan needs more care than one with a sapphire or ruby. A bezel that wraps the edges is the sensible choice, and a pendant is gentler still.

The stone is a lighter red with a warm orange lean. At almost six carats it reads clearly on the hand, which suits a ring for either a man or a woman.

Waxing is frequent in coral and some is dyed. Ask us about AG-RC-0005 and we will tell you what we know.

For cleaning, wipe it with a soft cloth dampened in plain water and dry it at once. Keep it clear of perfume, hairspray, chlorinated water and strong detergents, and store it in a pouch of its own so harder stones cannot mark it. Take it off before washing up or swimming.

This particular stone

This listing is one natural red coral, known in Urdu as Marjan, with a weight of 5.95 Carat. Its price is Rs. 8,250 — roughly Rs. 1,387 for each carat. Treatment: treatment not tested. Quote reference AG-RC-0005 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.
