Five carats is the size most people in Pakistan end up buying for a ring, and it is worth understanding why before you compare prices. Below about four carats an amethyst starts to look modest once it is bezelled in silver; much above eight and it begins to sit high on the finger and catch on clothing. A 5 carat stone sits in the middle of that practical range, which is also where the per-carat rate for amethyst is at its most competitive.

What you are buying

This is one stone, not a batch. It weighs 5 carats — 5.49 ratti on the traditional scale, where one ratti is 0.91 carat — and it is faceted, so the colour is broken up by the facets rather than sitting flat. The body colour is purple. The price is Rs. 13,130, which works out at roughly Rs. 2,626 per carat, and it is listed under reference GS-000256.

What a 5 carat amethyst looks like on the hand

People read carats as a number and then get a surprise when the parcel arrives, so here is the practical version. A 5 carat faceted amethyst covers most of the width of an average adult finger. In a silver bezel it reads as a proper gemstone ring rather than a dress ring, and it still passes under a shirt cuff. It is the size a jeweller will assume you mean if you walk in and ask for "a Jamunia for a ring" without saying anything else.

How to judge a purple amethyst

Four things move the price, in this order:

• Colour. An even, medium purple that holds its colour under indoor light is the most wanted. Stones that go grey or washed-out indoors sell for noticeably less, and so do stones where the colour sits in visible bands.
• Clarity. Amethyst is commonly eye-clean. Visible veils or fractures should pull the price down, not stay hidden in the photograph.
• Cut. A centred, symmetrical face without a dull flat window in the middle is what you want. A window means light passes straight through instead of bouncing back at you.
• Size. Amethyst is not rare at any size, so the per-carat rate rises far more gently with weight than it does for sapphire or ruby.

Heat, and what we can honestly say

Part of the amethyst on the market has been gently warmed to even out or lighten the colour. The trade treats this as normal and stable. We have not had this particular stone tested, so our specification sheet says "treatment not tested" rather than claiming it is untreated — we would rather be accurate than flattering. If the answer matters to you, we can arrange independent laboratory testing, and because you pay on delivery you can also take the stone to a laboratory of your own choosing inside the seven-day return window.

Will it survive daily wear?

Amethyst is 7 on the Mohs scale. That is hard enough for a ring worn every day, but not so hard that it ignores abuse — keep it away from household bleach, take it off before heavy work, and clean it with warm water, a drop of soap and a soft brush. Strong, prolonged sunlight can pale purple quartz over years, so a drawer is better than a windowsill.

What does it cost to get it set?

A 5 carat stone fits a standard gents' or ladies' silver ring without special work. Tell us the finger size and the style you have in mind and we will quote the setting separately from the stone, so you can see what each part costs.

Buying it

Delivery is a flat Rs. 500 anywhere in Pakistan by insured, tracked courier, dispatched within one to two working days. You pay the rider after you have opened the parcel and looked at the stone, and you have seven days to send it back unused if it is not what you pictured. A certificate of authenticity is available on request.

If you are still comparing, the full amethyst collection shows every stone we have in stock with its own per-carat rate, and our gemstone price guide explains how those rates are set. The amethyst care guide covers cleaning and storage in more detail.

This particular stone

This listing is one natural amethyst, known in Urdu as Jamunia, with a weight of 5 Carat. Its price is Rs. 13,130 — roughly Rs. 2,626 for each carat. Treatment: treatment not tested. Quote reference GS-000256 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.

Between two and six carats is the range most people choose for a gents' ring or a noticeable pendant. Here colour drives the price more than size does, which is why two stones of near-identical weight can be priced very differently.

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.
