Jamunia takes its name from jamun, the dark purple fruit, and a deep stone is the one that earns the name. Most of what is sold as Jamunia in local markets is a good deal lighter than the fruit it is named after. This one sits at the deep end of the range, which is where the price per carat starts to climb.

The stone

9.15 carats, which is 10.05 ratti. Faceted, in a deep purple. Rs. 16,500, about Rs. 1,803 per carat, reference GS-000240. One piece, photographed as it is.

At Rs. 1,803 per carat this is near the top of our amethyst range, and the reason is colour alone — larger stones in the same collection sit closer to Rs. 1,500 because size does not command a premium in amethyst the way saturation does.

How deep is too deep

There is a point where depth stops helping. Very dark amethyst — the material sometimes marketed as Siberian grade — can close up entirely under evening light and read as black. The stones worth owning are dense enough to look serious in daylight and still open enough to let light travel through them indoors. Judge it the way you will wear it:

• Daylight near a window. Everything looks good here. This tells you least.
• Ordinary room light in the evening. The real test. A deep purple should stay purple, not turn to a dark grey smudge.
• Under a phone torch. Shows you the colour the stone is capable of, and whether there is banding hiding in it.

Ask us on WhatsApp at +92 308 887 3888 for a video under ordinary room light and you can run the second test before it ships.

Setting a deep stone

Two decisions matter more than the rest. Ask for an open back, so light enters from behind and keeps the colour alive — a closed back makes a deep stone noticeably darker. And favour white metal: 925 silver, white gold or platinum lift a deep purple, while yellow gold pushes it further towards brown. At 9.15 carats it suits a men's silver ring in the traditional style, a cocktail ring, or a substantial pendant.

Does deep colour mean it has been treated?

Not by itself. Amethyst occurs naturally across the whole range, and heating is more often used to lighten or to convert material than to deepen it. We have not tested this stone, so the specification reads "treatment not tested" instead of a claim in either direction. Independent laboratory testing can be arranged, and a certificate of authenticity comes on request.

What else is not recorded?

Shape, measurements and clarity grade. We leave those fields honest rather than filling them with plausible values — ask and we will measure the stone and photograph it against a scale. Our authenticity page explains how stones are inspected before listing.

This particular stone

This listing is one natural amethyst, known in Urdu as Jamunia, with a weight of 9.15 Carat. Its price is Rs. 16,500 — roughly Rs. 1,803 for each carat. Treatment: treatment not tested. Quote reference GS-000240 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. As general background (not a statement about this stone): Amethyst is usually untreated, though some stones are heated to lighten the colour. Ask us on WhatsApp and we will tell you what we know about this exact stone; independent lab testing is available on request.

A certificate of authenticity is available on request for this stone, and independent laboratory testing can be arranged. Because you pay on delivery, you can also take the stone to a lab of your choice within the 7-day return window. Read more on our authenticity page.
