A 32 carat labradorite with a broad blue flash across much of its face. Here is what the stone offers and what to check before you buy.

• Weight 32 carats, at a rate per carat in line with the rest of our labradorite.
• A blue flash covering most of the dome, visible when you tilt it under a single light.
• Hardness 6 to 6.5 on the Mohs scale, so quartz dust and sand can scratch it.
• On arrival, check the edge for chips, since feldspar can split.
• Hold it by the sides and turn it under a window: the flash should appear across a range of angles, not just one.

To ask about it, message us on WhatsApp quoting GSN-LB-14. The stone is large enough to carry a heavy silver pendant or sit in a collector's display.

This particular stone

This listing is one natural labradorite with a weight of 32 Carat. Its price is Rs. 5,180 — roughly Rs. 162 for each carat. Treatment: treatment not tested. Quote reference GSN-LB-14 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.
