Every week somebody asks us for a certified amethyst, and it is worth being precise about what that word buys you. A certificate is a written opinion of what a stone is: species, whether it is natural or synthetic, and what treatment it shows. It is not a quality grade and it is not a valuation. This stone is sold certified, and an independent laboratory report can be arranged on top of that if you want a second, third-party opinion.

This stone on paper

7.70 carats — 8.46 ratti — in purple, listed at Rs. 5,780 under reference GS-000254. That is about Rs. 751 per carat. The reason is visible in the photograph rather than hidden in the paperwork: this piece has not been recorded as faceted, and its colour and finish sit below our top amethysts. If you want a large certified stone for a ring and the rate matters more than a showroom polish, this is the one to look at.

What certification actually covers

• Species and variety. That it is quartz, and that the variety is amethyst — not purple glass, not synthetic quartz, not dyed agate.
• Natural or laboratory-grown. The distinction that matters most, and the one you cannot reliably make by eye.
• Weight and measurements. Independently taken, which matters if you intend to insure the finished ring.
• Treatment, where it has been tested. Our own sheet for this stone still reads "treatment not tested", so if heat matters to you, ask for a laboratory report that covers it specifically.

What no certificate will tell you is whether the stone is worth the money. That is a judgement about colour, cut and the market, and you make it by looking — which is exactly what Cash on Delivery is for here.

Setting a 7.70 carat stone in a ring

At nearly eight carats this is a statement ring rather than an everyday band. In 925 silver it suits a broad shank and a bezel, or a four-claw setting with a solid gallery underneath, because the weight needs support. Expect it to sit a few millimetres proud of the finger. If you want it set, tell us your finger size on WhatsApp at +92 308 887 3888 and we will quote the mount separately so you can see what each part costs.

Can I take it to my own jeweller to check?

Yes, and we would rather you did. A certificate is worth more when you have verified it yourself. You pay the rider only after the parcel is open, and the seven-day return window runs from delivery, so there is time to get a second opinion before the sale is final. Our authenticity page explains how we inspect stones before listing them.

Why is the per-carat rate so much lower than your other amethysts?

Because amethyst is priced on appearance, not weight or paperwork. A clean, well-cut, saturated stone of the same size can cost three or four times as much per carat, certified or not. Compare it directly against the rest of the amethyst collection — each listing shows its own rate — and the difference will be plain.

This particular stone

This listing is one natural amethyst, known in Urdu as Jamunia, with a weight of 7.7 Carat. Its price is Rs. 5,780 — roughly Rs. 751 for each carat. Treatment: treatment not tested. Quote reference GS-000254 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.
