Topaz rates 8 on the Mohs scale, which puts it comfortably above quartz and well above glass, so a ring stone like this one survives ordinary wear without clouding from scratches. What it does not tolerate is a hard blow to a corner, because topaz has a cleavage plane that lets it split.

For this 7.9 carat white topaz, that means thinking about the setting before you buy. A pendant carries little risk. A ring is fine if the metal covers the edges, and it is less wise for someone who works with their hands. The stone is priced at Rs. 7,130, about Rs. 903 per carat, reference GS-WH-0007.

The stone is natural, colourless topaz, which is normally not treated, and if you ask on WhatsApp we will tell you what we know about this exact piece. Independent lab testing is available on request.

Cleaning and storage

Warm water, a little mild soap and a soft toothbrush are enough. Rinse, dry with a lint-free cloth and keep the stone in a separate pouch so that harder gems like sapphire cannot scratch it. Our white topaz care guide covers more, and other weights are under white topaz.

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.
