Start by asking how you will wear it. An 18.25 carat labradorite is a pendant stone first, and its size makes that clear. In silver it looks understated; in gold, a little more formal.

Labradorite is a feldspar, a little softer than quartz at 6 to 6.5 on the Mohs scale. It can chip if struck on an edge, and harder gems will scratch it. Avoid ultrasonic cleaners; plain water and a soft cloth are enough.

Has it been treated?

The gem is rarely enhanced, but ask us rather than assume. Message us on WhatsApp quoting GSN-LB-04 and we will pass on whatever we know. If you would like independent lab testing, that is your choice.

When you want to compare, open the labradorite page.

Think of it as a larger, quieter stone that rewards good light and a steady chain. Tilt it slowly under a window and the flash will come and go across the dome.

It travels by tracked, insured courier. Karachi orders usually arrive within 1 to 2 working days, Lahore, Islamabad and the other major cities within 2 to 4, and smaller towns can take up to about a week.

Open the parcel, check the stone, then pay; 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 18.25 Carat. Its price is Rs. 3,150 — roughly Rs. 173 for each carat. Treatment: treatment not tested. Quote reference GSN-LB-04 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.
