Some people want one bold stone instead of several small ones, and this 17.75 carat jamunia is for them. Think of a cocktail ring, a heavy pendant, or a piece you plan to have made to your own design. At this size the purple has room to show.

What you are getting

It is a natural amethyst, laser cut, weighing 17.75 carats. Amethyst is quartz, so it rates 7 on the Mohs scale: hard enough for daily wear, though a ring should still be kept away from hard knocks. Message us on WhatsApp quoting AG-000239 and we will send fresh photographs taken in natural light.

Before you decide

Amethyst is usually left as it came out of the ground, but some stones are heated to lighten their colour. Ask us about this one and we will tell you what we know; an independent lab test is your option. Vedic astrology links jamunia with Saturn, and by tradition it is worn on an astrologer's advice.

Because it ships Cash on Delivery, you can open the parcel and inspect the stone before you pay. Keep it away from long, direct sunlight, since strong light over many months can pale the purple of any amethyst.

Karachi usually receives it in 1–2 working days and other cities in 2–4; you pay after checking, and returns are open for 7 days. Read our amethyst guide before choosing.

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.
