In this gem family, anything over twenty carats starts to read as a statement stone, and at 21.25 carats this labradorite is exactly that. As a ring it covers a good part of the finger, and on a pendant it becomes the centre of attention. It is still comfortable to wear, because labradorite is not a dense material.

The thing to judge is saturation. A deep, electric blue flash counts for more than a pale one, and for more than size: a twenty-carat stone with real intensity beats a thirty-carat stone with a washed-out sheen.

This stone has the most saturated blue we hold in the current group, on a cabochon dome. Its rate per carat is a little lower than the smaller labradorites, as you would expect for the size.

At 6 to 6.5 on the Mohs scale, with two cleavage directions, treat it kindly: a bezel setting, occasional wear, and a damp cloth to clean.

This particular stone

This listing is one natural labradorite with a weight of 21.25 Carat. Its price is Rs. 3,450 — roughly Rs. 162 for each carat. Treatment: treatment not tested. Quote reference GSN-LB-07 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.
