This labradorite comes from Madagascar, one of the better-known sources of the gem. At 21.70 carats it is also among the heavier labradorites in this group.

Treat it as a showpiece. Labradorite is prized for the shifting play of colour it shows when tilted, and a stone this big gives that effect plenty of room. With a hardness of 6 to 6.5 on the Mohs scale, a pendant is the sensible form, with a ring reserved for careful wearers.

Labradorite is generally sold without treatment. For details specific to this stone, message us on WhatsApp quoting GSN-LB-08. Independent lab testing is your choice.

The best way to appreciate it is to compare it with the smaller pieces in our labradorite section and decide which size you would actually wear.

Delivery is a flat Rs. 500 for the whole order, so adding a second stone does not raise the fee.

A stone this large is best shown off on its own, with no other pendants crowding it. Wipe it with a damp cloth and store it in a soft pouch.

Cash on Delivery lets you open the parcel and see the flash for yourself before paying. Karachi orders usually arrive in 1 to 2 working days, the rest of Pakistan in 2 to 4, and unused stones can be returned within 7 days. Before you choose, read our labradorite guide.

This particular stone

This listing is one natural labradorite with a weight of 21.7 Carat. Its price is Rs. 3,680 — roughly Rs. 170 for each carat. Origin: Madagascar. Treatment: treatment not tested. Quote reference GSN-LB-08 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 labradorite 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 labradorite 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 labradorite 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.
