Any dealer will tell you that dyeing is a regular part of the yellow agate trade, and that is the first thing a careful buyer should raise. It is nothing to be embarrassed about; it is simply how much of this stone reaches the market, and the right response is to ask.

We are happy to be asked. For this 18.75 carat piece, message us on WhatsApp with the reference GS-YE-0016 and we will tell you what we know about this exact stone. If you want a written result, independent lab testing can be arranged on request.

Beyond that question, the facts are straightforward. It is a natural yellow agate of 18.75 carats, with a Mohs hardness of 6.5 to 7, listed at Rs. 2,700, about Rs. 144 per carat. The weight suits a broad gents' ring or a pendant better than a thin band.

A soft pouch and an occasional wipe with a damp cloth are all the care it needs. It belongs to our yellow agate collection, where you will find other sizes at similar per-carat rates.

Cash on Delivery is available across Pakistan, so you inspect the stone before paying, and returns are accepted within 7 days of delivery. Before you choose, read our yellow agate guide.

This particular stone

This listing is one natural yellow agate with a weight of 18.75 Carat. Its price is Rs. 2,700 — roughly Rs. 144 for each carat. Treatment: treatment not tested. Quote reference GS-YE-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.

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 yellow 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 yellow 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 yellow 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.
