This 8.65 carat black agate suits someone who wants a ring stone big enough to notice but not so big that it gets in the way. It is a comfortable size, large enough to read clearly across the hand, and light enough to forget you are wearing it.

Why it works as a ring

Hardness of 6.5 to 7 on the Mohs scale gives it good resistance to scratches, and a dense black tone hides small marks better than a pale stone would. A bezel setting in silver is the usual choice; a custom silver ring setting can be discussed on WhatsApp.

Before you buy

The black comes from dyeing, which is how black agate is normally prepared, so the stone should be judged on its polish and its edges. The price is Rs. 1,500 and the rate is about Rs. 173 per carat. Please quote GS-BL-0016 to us. You will find similar stones in the black agate section.

A weight like this will also look good as a pendant if you would rather not wear it on the hand, and the same bezel idea applies.

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 black agate guide.

This particular stone

This listing is one natural black agate with a weight of 8.65 Carat. Its price is Rs. 1,500 — roughly Rs. 173 for each carat. Treatment: treatment not tested. Quote reference GS-BL-0016 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.

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 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.
