Somewhere around eight and a half carats, white topaz stops looking like a delicate accent and starts to look like a proper centre stone. At 8.70 carats this one is on the larger side of mid-sized. Topaz does grow big, so the size is not rare the way a large ruby would be, but on a hand it reads clearly and works best in a ring with some presence or in a pendant.

If you are buying for a smaller hand or for wear around the house, bear in mind that a heavier stone sits higher and catches more knocks.

What to look for

Because the stone has no colour, judge it on brightness, a clean interior and a good polish, and check the edges for chips. Topaz measures 8 on the Mohs scale and is normally sold as it comes from the ground. Message us on WhatsApp quoting AG-WH-0009 and we will tell you what we know about this particular piece.

This particular stone

This listing is one natural white topaz with a weight of 8.7 Carat. Its price is Rs. 7,880 — roughly Rs. 906 for each carat. Treatment: treatment not tested. Quote reference AG-WH-0009 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 white topaz rates 8. Few materials will scratch it, so it copes well with everyday ring wear. A soak in warm water with a drop of mild soap and a soft brush keeps it bright; skip the ultrasonic cleaner if inclusions reach the surface.

Whoever you buy white topaz 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 white topaz for those three points before it is listed, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
