A 1.8 carat peridot — 1.98 ratti — at Rs. 3,000, or about Rs. 1,667 per carat. That is the lowest per-carat rate in this collection, so it is the right page on which to set out what peridot actually costs.

The real spread

Across our fifteen peridots the rate runs from Rs. 1,667 to Rs. 5,385 per carat — a spread of more than three times. Total prices run from Rs. 1,880 to Rs. 30,750. That is a far wider range than most of our categories show, and the reason is that peridot is judged on several things at once rather than mainly on weight.

What moves a peridot's price

Colour first. Pure grass or bottle green with little yellow commands the most. Our stones measure between 25% and 99% green coverage, and the difference is visible across a table.

Then cutting. Peridot's strong double refraction makes it unforgiving: a poorly placed table leaves the stone looking soft. Our facet share figures run from 1.9% to 10.2%, separating smooth polished domes from sharply faceted stones.

Then size. Peridot above five carat is markedly scarcer, and the per-carat rate rises rather than staying flat.

Clarity last, because peridot is usually eye-clean and so it discriminates less between stones than colour or cut do.

This stone

Green covers 89% of it — well toward the pure end — with a facet share of 4.8%, mid-range between the smooth domes and the sharply faceted stones. At under two carats and the keenest rate here, it is the sensible entry point into the category.

Care

Peridot is 6.5 to 7 on the Mohs scale. Never an ultrasonic cleaner, never steam, and avoid sudden temperature change and household acids.

Recorded as an Afghan stone. Treatment has not been tested on this piece, which we record plainly rather than calling it untreated. Dimensions and clarity are not recorded yet; ask and we will measure.

This particular stone

This listing is one natural peridot, known in Urdu as Zabarjad, with a weight of 1.8 Carat. Its price is Rs. 3,000 — roughly Rs. 1,667 for each carat. Origin: Afghanistan. Treatment: treatment not tested. Quote reference GS-00055 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.

Under two carats, a stone like this sits neatly in a slim ring, a stud or a delicate pendant and does not snag on sleeves. It is also where many first-time buyers begin when a stone is recommended for astrological reasons, because the total cost stays modest.

On the Mohs scale peridot rates 6.5 to 7. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy peridot 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 peridot 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.
