19.40 carats — 21.32 ratti — at Rs. 7,280, about Rs. 375 per carat. The reference is GSN-LL-28.

What the photograph actually shows

Saturation measures 83%, among the strongest readings in the collection, and brightness 74 out of 255 — so this is a bright, vivid blue rather than a dark one. Pale calcite accounts for 5.6% of the surface, appearing as light threading rather than solid white.

A bright saturated blue is the easiest lapis to wear. Dark stones look superb in daylight and can turn almost black under a lamp; this one keeps its colour indoors.

Sizing a lapis to a ring

Around 15 to 20 carats is the practical band for a ring stone. Below it a cabochon starts to look lost in a bezel heavy enough to protect it; much above and the ring catches on things, which matters more with lapis than with a hard stone, because every knock counts.

At 19.40 carats this sits at the upper end of that band — a proper statement without tipping into pendant territory.

Setting advice

A bezel rather than claws, in silver. Lapis is 5 to 5.5 on the Mohs scale, softer than a steel blade, so the mount needs to do the protecting. Ask your jeweller to keep the bezel wall slightly proud of the dome at the girdle.

Care

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

We have not had this stone tested, so its treatment is recorded as "not tested" rather than untreated, and we hold no documented origin for it. Lapis is often dyed or waxed — message +92 308 887 3888 if you would like an identification first. The rest of the range is in the lapis lazuli category.

This particular stone

This listing is one natural lapis lazuli, known in Urdu as Lajward, with a weight of 19.4 Carat. Its price is Rs. 7,280 — roughly Rs. 375 for each carat. Treatment: treatment not tested. Quote reference GSN-LL-28 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.
