This 10.65 carat Ceylon moonstone — 11.70 ratti — is Rs. 6,600, or about Rs. 620 per carat. Since people usually arrive at this page asking what a moonstone should cost, here is the honest answer rather than a sales line.

What moonstone actually costs here

Across the twenty moonstones in this collection the rate runs from about Rs. 481 to Rs. 776 per carat. That is the real spread, and this stone at Rs. 620 sits comfortably below the middle of it. Total price follows weight, so the same rate buys a very different object: our smallest stones land near Rs. 6,600 and the largest reaches Rs. 21,000. When you compare sellers, compare the per-carat rate rather than the ticket price, because a cheap total usually just means a small stone.

What moves the rate

Three things, mostly. Body clarity, because a translucent stone that passes light is worth more than a cloudy one. The strength of the adularescence — how bright the blue is and how far it travels across the dome. And size, since large clean rough is scarcer than small, which is why big stones normally carry a premium per carat rather than a discount. Origin matters to buyers too; Ceylon has been the benchmark source for adularia moonstone for over a century and the name still moves prices.

What this particular stone gives you

Ten and a half carats is a genuinely useful size: large enough for the sheen to have room to move across the dome, small enough to wear in a ring without the stone standing proud and catching. It is the weight we most often recommend to someone buying their first serious moonstone rather than a starter piece.

Care

Moonstone is 6 to 6.5 on the Mohs scale with good cleavage, so sharp knocks are a bigger risk than scratches. Warm water, mild soap, soft cloth. No ultrasonic cleaner, no steam, no bleach. Store it apart from harder stones. Treatment has not been tested on this piece — we record that plainly rather than describing it as untreated. Dimensions and clarity are not recorded yet; ask and we will measure.

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.
