Somewhere around twelve carats, amethyst stops being a small gem and becomes a feature. This 12.8 carat stone sits well above the middle of the family's size range, so wearing it is really a decision about how much attention you want.

A larger stone holds its colour more deeply, so a purple that would look pale in a small stone can read well at this size. With any big amethyst, check for an even colour through the body, no pale zones, a clean cut and no chipped edges. This one is purple with a laser cut; look at the facets in daylight when it arrives.

The reference is AG-000238. Large amethysts usually carry lower per-carat rates than small ones, so the total stays easy on the pocket for the size.

It is a natural stone. Most amethyst sells as found, though a few are warmed to lighten them, and we can share what we know on WhatsApp. For wear, a closed-back silver setting protects it, and at 7 on the Mohs scale it is happy with occasional use. Other weights are in the amethyst range.

With Cash on Delivery you look first and pay after; Karachi orders usually arrive in 1–2 working days, other cities in 2–4, with 7 days to return. See our amethyst guide.

This particular stone

This listing is one natural amethyst, known in Urdu as Jamunia, with a weight of 12.8 Carat. Its price is Rs. 18,380 — roughly Rs. 1,436 for each carat. Treatment: treatment not tested. Quote reference AG-000238 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 amethyst rates 7. It handles daily wear, but a hard knock can still nick an exposed corner, so a protective setting is a sensible choice. Clean it with warm soapy water and a soft brush, and keep it away from abrasive cleaners and high heat.

Whoever you buy amethyst 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.
