Seven point eight carats of purple quartz, cut by laser into a shape that catches light from every angle: that is this stone in one breath. It is a natural amethyst, called Jamunia in Urdu, and it costs Rs. 13,880.

That price comes to roughly Rs. 1,779 per carat, which is a useful figure if you are comparing it with other amethysts on our amethyst page. The reference is GS-000248, handy when you message us on WhatsApp.

Hardness is 7 on the Mohs scale. That makes it practical for most jewellery, from pendants to rings worn with a little thought. Dust and body oils dull any gem over time, so a quick wipe with a soft cloth keeps the colour lively.

On treatment, we can tell you what we know about this exact stone if you ask; the family is mostly sold unaltered, with occasional heating to lighten colour. In Vedic astrology, Jamunia is associated with Saturn, a belief held by many buyers who choose it.

Delivery is Cash on Delivery with inspection before payment, and a 7-day return window follows.

This particular stone

This listing is one natural amethyst, known in Urdu as Jamunia, with a weight of 7.8 Carat. Its price is Rs. 13,880 — roughly Rs. 1,779 for each carat. Treatment: treatment not tested. Quote reference GS-000248 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 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. We check every amethyst 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request.
