Topaz is 8 on the Mohs scale against sapphire's 9, and it costs a good deal less. Topaz is also called sunehla. Both are used in Jupiter-related jewellery according to Vedic belief.

This stone is a natural topaz of 4.60 carats in yellow, listed from Katlang.

On the Mohs scale 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 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 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.
