Moonstone with a clean, even glow rarely comes very large, which makes 6.75 carats something of a sweet spot. The blue sheen is easy to see at this size, and the stone stays comfortable in a pendant.

It is from Ceylon (Sri Lanka), milky white and translucent, with a bluish adularescence. Mohs hardness is 6 to 6.5 and it can cleave if struck, so a pendant, earrings or a protected ring setting makes sense.

Judging a moonstone

Look for an even glow with no cracks running through the body, and a sheen that moves as you tilt the stone. Check the edges for tiny chips. Hold it against a window: the light should look soft and floating, as if it sits just under the surface.

Moonstone is seldom treated. Ask us what we know about this exact stone, quoting AG-000402, and if you want independent lab testing, that is your call. See other moonstones to compare size and sheen.

No advance payment is needed. We dispatch on Cash on Delivery, you inspect before paying, Karachi addresses usually receive it in 1–2 working days and other cities in 2–4, and a 7-day return is there as a safety net. Our moonstone guide has care tips.

This particular stone

This listing is one natural moonstone with a weight of 6.75 Carat. Its price is Rs. 4,880 — roughly Rs. 723 for each carat. Origin: Ceylon (Sri Lanka). Treatment: treatment not tested. Quote reference AG-000402 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, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
