For 5.60 carats of black agate, Rs. 900 comes to about Rs. 161 per carat. In this family that sits in the middle of the pack, since black agate prices tend to move with size and the quality of the polish rather than with any rare colour. A per-carat figure in the low hundreds is typical for the stone, so it is a comparison point, not a bargain alarm.

Colour and shape of use

The colour is black, achieved by dyeing, which is how almost all black agate is sold. At this weight the stone suits a slim silver band or a ladies' ring.

Setting

Agate at 6.5 to 7 Mohs is sturdy enough for a ring. A closed-back bezel keeps the surface clean and shields the edge. You can discuss a custom silver ring setting with us on WhatsApp.

This particular stone

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 black 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 black 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 black 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.
