"Genuine" is a word worth unpacking before you buy any blue topaz, because it means something precise here and something looser almost everywhere else. This page says exactly what it means for this stone, and then gets on with the pendant.

The stone

9.75 carats, which is 10.71 ratti. Shape: oval, faceted. Recorded colour: blue. Rs. 19,500, Rs. 2,000 per carat, reference GS-00068.

What genuine means for blue topaz

• It is a real topaz crystal. Natural, mined, not glass, not synthetic spinel, not a doublet. That is what genuine properly refers to.
• The colour is treated. Blue topaz gets its colour from irradiation and heating — standard for the stone and stated on our specification sheet. It begins as colourless topaz, which is common and inexpensive.
• Both things are true at once. A genuine topaz with a treated colour is the normal state of affairs for effectively all blue topaz sold anywhere in the world. Natural blue topaz exists, but it is very rare and very pale — nothing like this.
• The colour is permanent. It does not fade with ordinary wear, and treated material is held until residual activity has decayed to safe levels before release.

So the honest claim is: genuine topaz, treated colour, stated openly. Anyone selling blue topaz as naturally blue at an ordinary price is not telling you the truth. Our blue topaz guide goes through the process.

Why a pendant suits this stone

Two reasons, one aesthetic and one practical. Aesthetically, a transparent bright blue needs light passing through it, and a pendant hangs where daylight reaches it rather than being shaded by a hand. Practically, topaz has perfect basal cleavage and a pendant takes a fraction of the knocks a ring does — it is simply the safer home for the stone.

Specifying it

Ask for an open back so light passes through and the colour stays bright; a closed back makes a transparent stone look flat and dark. A bezel with an integrated bail is the cleanest and most secure mount, and the rim protects the girdle. 925 silver or white gold keeps the blue exactly as photographed; yellow gold warms it slightly green. A 16 to 18 inch chain sits at the collarbone and suits a single stone of this size.

Care

Topaz is 8 on the Mohs scale, so scratching is rarely the problem — the cleavage is. Never use an ultrasonic or steam cleaner. Warm soapy water and a soft brush. Store it apart from harder stones. Full routine in our topaz care guide.

Verification

A certificate of authenticity is available on request and independent laboratory testing can be arranged — a report will confirm the species and that the colour is treated.

This particular stone

This listing is one natural blue topaz with a weight of 9.75 Carat. Its price is Rs. 19,500 — roughly Rs. 2,000 for each carat. Treatment: irradiated & heated. Quote reference GS-00068 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 blue 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 blue 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 blue topaz 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Irradiated & heated. Certificate available on request. As general background (not a statement about this stone): Blue topaz gets its blue colour from irradiation and heating — this is standard for the stone and the colour is stable.
