19.90 carats — 21.87 ratti — at Rs. 7,460, about Rs. 375 per carat. The reference is GSN-LL-29.

Why this one suits a man's silver ring

Three reasons, and they are measurable. Brightness reads 59 out of 255, putting it among the darker stones here, and a deep blue holds its own against the weight of a heavy silver mount where a pale stone would look lost. Saturation measures 82%, so the colour is strong enough not to go grey under indoor light. And pale calcite is only 5.4% of the face, so there is no distracting white banding.

Twenty carats is also the right size. Large enough to read properly across the back of a hand, not so large that the ring becomes a nuisance.

Setting advice

A bezel, not claws. Lapis is soft — 5 to 5.5 on the Mohs scale, softer than window glass — and claws put all the holding pressure on four small points. A bezel wraps the girdle and spreads it. Oxidised or antiqued silver suits a deep blue better than a high polish, which can make the stone look flat by comparison.

Take the ring off for anything rough. A knock that a sapphire would shrug off will mark a lapis.

Care

Warm water and a soft cloth. No ultrasonic cleaner, no steam, and keep it away from perfume, hairspray and household cleaners.

This particular stone

This listing is one natural lapis lazuli, known in Urdu as Lajward, with a weight of 19.9 Carat. Its price is Rs. 7,460 — roughly Rs. 375 for each carat. Treatment: treatment not tested. Quote reference GSN-LL-29 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 lapis lazuli rates 5 to 6. That makes it soft for a gemstone, better suited to pendants, earrings and rings for special occasions than to a daily ring. Keep it away from perfume, cleaning products, steam and ultrasonic cleaners, and polish it with a dry, soft cloth after wear.

Whoever you buy lapis lazuli 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 lapis lazuli 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.
