Wondering how to set a 7.20 carat black agate? These are the options we usually suggest.

A simple silver ring is the first one. The stone is compact enough to sit well in a slim band, and a bezel will protect its edge. If you want something heavier, gold is the alternative, and black looks sharp against it. For a pendant, a small bail and bezel keep the stone secure and let it hang flat.

A custom silver ring setting can be talked through with us on WhatsApp. We will not quote a price or a date until we have discussed what you want.

Know the stone

This piece is Kala Aqeeq, a natural black agate of 7.20 carats at Rs. 1,350 (about Rs. 188 per carat). Mohs hardness is 6.5 to 7, so daily wear is reasonable. The colour is dyed, which is simply standard for black agate. When you message us, mention GS-BL-0013. See other options in the black agate collection.

If you cannot decide between silver and gold, think about the wearer's other jewellery. Matching the metal to what he or she already wears usually settles it.

This particular stone

This listing is one natural black agate with a weight of 7.2 Carat. Its price is Rs. 1,350 — roughly Rs. 188 for each carat. Treatment: treatment not tested. Quote reference GS-BL-0013 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.
