This is a larger moonstone: 13.25 carats from Ceylon (Sri Lanka), priced at Rs. 8,630, or about Rs. 651 per carat. What follows is what we know and what to check when it reaches you.

• Colour: a milky white body with a bluish adularescence that shifts as you tilt it.
• Transparency: translucent; the glow seems to come from inside the stone, not from a mirror-like surface.
• Hardness: 6 to 6.5 on the Mohs scale, so keep it clear of rough knocks and hard worktops.
• Treatment: moonstone is generally not enhanced, and we will gladly share our notes on this stone over WhatsApp.
• On arrival: open the parcel in front of the courier, turn the stone in daylight and look for the blue sheen at more than one angle.
• Reference: GS-000409.

A stone of this weight has real presence on a pendant, and it fills a larger ring face well if the setting protects the edges. A test at an independent lab can be arranged, and you have seven days from delivery to decide. More moonstones to compare are in the moonstone range.

This particular stone

This listing is one natural moonstone with a weight of 13.25 Carat. Its price is Rs. 8,630 — roughly Rs. 651 for each carat. Origin: Ceylon (Sri Lanka). Treatment: treatment not tested. Quote reference GS-000409 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.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

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.
