Black agate is priced mostly by size and the quality of its polish, not by any rare colour, so stones in this family sit close together on price. This 5.60 carat piece is in the middle of the pack, which makes it a useful comparison point rather than an outlier.

Colour and size

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

Setting

At 6.5 to 7 on the Mohs scale, agate 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 with us on WhatsApp; mention AG-BL-0009 so we can pull up this exact piece.

There is no pressure to decide from a photograph alone. You see the stone at your door before paying, and you can judge the polish and the evenness of the black in daylight.

This particular stone

Quote reference AG-BL-0009 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 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, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
