This particular stone

This listing is one natural red agate with a weight of 13.75 Carat. Its price is Rs. 1,880 — roughly Rs. 137 for each carat. Treatment: treatment not tested. Quote reference AG-RE-0011 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.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

On the Mohs scale red 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 red 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 red 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.
