This 5.10 carat red agate is a small, easy stone. Below are the points we would check, and would encourage you to check too, when it reaches you.

• Weight: 5.10 carats, priced at Rs. 770 (about Rs. 151 per carat).
• Hardness: 6.5 to 7 Mohs, fine for a ring with sensible care.
• Colour: look at it in daylight, not under a shop bulb, since red agate can change tone with the light source.
• Treatment: red agate is frequently heated or dyed, so ask us what we know about stone GS-RE-0002.
• Surface: run a fingertip over it and look for chips along the edge.

Small red agates like this one suit a ladies' ring or a slim silver band, and the Surkh Aqeeq name will be familiar to anyone who has shopped for aqeeq in Pakistan. Find our other sizes in the red agate section, or write on WhatsApp +92 308 887 3888 if you want a closer look before ordering.

Because it is so light, a stone of this size also works as a small drop pendant, where a thin silver loop is all the mounting it needs. Photographs flatter or dull colour, so trust your eyes once it is in your hand.

Pay Cash on Delivery once you have opened the parcel and seen the stone yourself, anywhere in Pakistan, with 7 days to return it if you change your mind. Before you choose, read our red agate guide.

This particular stone

This listing is one natural red agate with a weight of 5.1 Carat. Its price is Rs. 770 — roughly Rs. 151 for each carat. Treatment: treatment not tested. Quote reference GS-RE-0002 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, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
