Treatment is the first thing a careful buyer should raise with any gemstone. With moonstone the position is reassuring but not absolute: the gem is normally sold as it comes, in contrast to sapphire, which is commonly heated, or emerald, which is commonly oiled. That describes the family, so for this 7.1 carat piece the right step is a WhatsApp message to us. We will share our notes on this exact stone, and an independent lab test can be organised.

What we can say about the stone is plain enough. It comes from Ceylon (Sri Lanka), with a milky white body and a bluish adularescence that appears as the light shifts. It weighs 7.1 carats and is priced at Rs. 4,500, which is about Rs. 634 per carat.

Hardness of 6 to 6.5 on the Mohs scale means you should treat it more gently than a ruby or a sapphire. A silver pendant is a natural home. For a ring, pick a protective bezel and avoid wearing it during heavy work. Reference GS-000416. Other moonstones to compare are in our moonstone collection.

This particular stone

This listing is one natural moonstone with a weight of 7.1 Carat. Its price is Rs. 4,500 — roughly Rs. 634 for each carat. Origin: Ceylon (Sri Lanka). Treatment: treatment not tested. Quote reference GS-000416 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 moonstone rates 6 to 6.5. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy moonstone 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 moonstone 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.
