A 2.45 carat round peridot — 2.69 ratti — at Rs. 11,250, about Rs. 4,592 per carat.

Round, and genuinely faceted

The outline measures 1.07 times as wide as tall — close to a true circle, against ovals in this collection running up to 1.36. Facet share reads 7.2%, among the highest of the fifteen, so this is a cut stone with well-defined facet junctions rather than a polished dome.

The round is the most demanding shape to cut well because it wastes the most rough: a round brilliant typically keeps less than half the weight of the crystal it came from. That is why rounds command a premium over ovals and cushions of the same weight, and why so much coloured stone is cut as ovals instead.

The colour is the best here

Green covers 99% of this stone, the highest in the collection alongside one other, and it carries the least yellow. Fine peridot is judged on exactly this: a pure grass or bottle green with as little yellow or brown as the material allows. Stones at this end are scarcer than the olive-greens, which is reflected in the rate.

Why peridot is always green

Its colour comes from iron that is part of the mineral's formula, not a trace impurity — peridot is gem-quality olivine, a magnesium-iron silicate. That is why no colourless peridot exists and why the only variation is how far toward yellow a stone sits.

Care

Peridot is 6.5 to 7 on the Mohs scale. Never an ultrasonic cleaner or steam — both are common causes of damage in peridot specifically, because they work on internal inclusions. Avoid sudden temperature change and household acids. Warm water, mild soap and a soft brush.

This particular stone

This listing is one natural peridot, known in Urdu as Zabarjad, with a weight of 2.45 Carat. Its price is Rs. 11,250 — roughly Rs. 4,592 for each carat. Origin: Afghanistan. Treatment: treatment not tested. Quote reference GS-00085 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 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.
