The most useful thing to know about these 11 carats is how they wear. Red agate is rated 6.5 to 7 on the Mohs scale: hard enough for a ring, not so hard you can ignore it. Quartz dust in the air is about 7, so over the years a little fine abrasion is possible on any agate that lives on a busy hand.

For a ring, choose a setting that holds the stone slightly proud of the skin but guarded at the edges. For a pendant, almost anything works. Wipe it with a damp soft cloth, avoid ultrasonic cleaners, and store it apart from harder gems so it is not scratched in a drawer.

The stone is a natural Surkh Aqeeq weighing 11 carats. Colour in red agate is often deepened by heating or dyeing, so ask what we know about AG-RE-0010 on WhatsApp.

At this size it suits a man's ring or a medium pendant equally well.

From six carats up a stone becomes the centre of attention. It wants a broader shank or a secure claw setting and suits an occasion ring, a signet or a centre pendant. Clean natural material of this size turns up far less often, and the per-carat rate reflects that.

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.
