Six point eight five carats, Rs. 6,230, and about Rs. 909 per carat: those three numbers sum up this white topaz, and they place it right in the middle of what colourless topaz normally costs in our shop.

What the numbers do not show is how the stone looks on the day it arrives. White topaz has no body colour, so what you notice is brightness. Hold it under a lamp and then by a window, and look for even sparkle across the whole stone. Check also whether the edges are clean, since a small chip would show quickly in a stone this clear.

The gem measures 8 on the Mohs scale, which suits a ring, and the usual precaution applies: topaz can split along its cleavage plane if struck sharply, so a bezel or a snug setting is better than exposed corners. Colourless topaz is normally not treated, and we will tell you what we know about this exact stone if you message us with reference GS-WH-0005.

Cash on Delivery allows inspection before payment, and the white topaz collection has more weights to compare.

Pay Cash on Delivery once you have opened the parcel and seen the stone yourself, anywhere in Pakistan, with 7 days to return it if you change your mind. Before you choose, read our white topaz guide.

This particular stone

This listing is one natural white topaz with a weight of 6.85 Carat. Its price is Rs. 6,230 — roughly Rs. 909 for each carat. Treatment: treatment not tested. Quote reference GS-WH-0005 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.
