This particular stone

This listing is one natural black agate with a weight of 5.1 Carat. Its price is Rs. 380 — roughly Rs. 75 for each carat. Treatment: treatment not tested. Quote reference AG-BL-0007 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.
