Hardness decides what you can do with a stone, so start there. Red agate sits at 6.5 to 7 on the Mohs scale, a little harder than a steel blade, which makes this 5.20 carat piece a sensible choice for a ring that will actually be worn.

Day to day, it shrugs off most scratches from keys and fabric, though a hard knock against a door frame can still chip an exposed edge. A silver setting with a slight rim around the stone gives it a margin of safety. A pendant asks even less of it.

The stone is a natural Surkh Aqeeq. Red agate is often heated or dyed to strengthen its colour, so we suggest asking about this one; message us on WhatsApp with the code AG-RE-0003.

Clean it with lukewarm water and a drop of mild soap, dry it with a soft cloth, and keep it in a pouch away from harder gems.

This particular stone

This listing is one natural red agate with a weight of 5.2 Carat. Its price is Rs. 780 — roughly Rs. 150 for each carat. Treatment: treatment not tested. Quote reference AG-RE-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 agate rates 6.5 to 7. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy red agate 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 agate 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.
