People ask for a certified blue topaz because they want to be sure it is not glass or synthetic. That is exactly the right instinct, and a report answers it. What a report will not do is tell you the colour is natural — and with blue topaz that distinction is the whole story.

The stone

9.20 carats, which is 10.11 ratti. Rs. 18,400, Rs. 2,000 per carat, reference GS-BT-0002.

What certification covers

• Species. That it is topaz — not glass, not synthetic spinel, not blue quartz, not a doublet. This is the line most buyers actually want.
• Natural or laboratory-grown. The crystal itself is mined. Synthetic topaz is not a commercial product, but the substitutes above are everywhere.
• Treatment. A report will note irradiation and heating. This is not a black mark; it is the normal finding for blue topaz.
• Weight and measurements. Independently taken, useful if you intend to insure the finished piece.

What no certificate does is grade the cut, and with blue topaz the cut is where stones actually differ, because the colour is consistent across the market.

The point worth being clear about

Blue topaz gets its colour from irradiation and heating. It starts as colourless topaz, which is abundant and cheap. The treatment is standard, permanent, and applied to effectively all blue topaz sold anywhere in the world. Treated material is held until residual activity has decayed to safe levels before release, which is a regulated requirement.

So "certified blue topaz" means the topaz is genuine topaz. It does not mean the blue arrived on its own. Naturally blue topaz exists but is rare and very pale, and it does not reach the market at Rs. 2,000 a carat.

How to get a report on this stone

Ask us on WhatsApp at +92 308 887 3888 and we will send it to an independent laboratory before dispatch and forward the report — we will tell you the delay first. Or take it to a laboratory of your own choosing after delivery: you pay the rider only once the parcel is open, and the seven-day return window runs from delivery, so the stone goes back unused if the result is not what you expected. Our lab-certified topaz page explains the process, and the authenticity page covers how we inspect stones before listing.

The check you can do yourself

Pick it up. Topaz is dense — noticeably heavier for its size than glass or quartz — and that single impression rules out most imitations before a loupe comes out. Then look for round gas bubbles and swirl lines under magnification, which glass shows and topaz does not.

Durability

Topaz is 8 on the Mohs scale with perfect basal cleavage: hard to scratch, splittable under a sharp knock. No ultrasonic or steam cleaning. Warm soapy water and a soft brush. See our topaz care guide.

Ordering

One piece only. Shape and measurements have not been recorded; we will measure it on request. Flat Rs. 500 delivery anywhere in Pakistan, insured and tracked, dispatched in one to two working days. Cash on Delivery, seven days to return it unused. More in the blue topaz collection.

This particular stone

This listing is one natural blue topaz with a weight of 9.2 Carat. Its price is Rs. 18,400 — roughly Rs. 2,000 for each carat. Treatment: irradiated & heated. Quote reference GS-BT-0002 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.
