The banding on this stone

Bright green bands curve in tight concentric arcs across the whole upper-right quarter, each one clearly separated from the next, and they are the brightest green on this page. A pale grey zone occupies the top-left corner. The centre is a deep, quiet green, and a softer pale-green area fills the bottom-left.

The contrast is what makes it: vivid banded green against near-black, with no muddy transition between them. On a lot of malachite those two zones blur into each other.

What "premium" means here

It means the best-defined banding and the sharpest light-to-dark contrast of the stones on this page — judged by eye against the other nineteen, because malachite offers nothing else to grade on. It does not mean a laboratory has graded it; nothing in this category has been tested, and we are not going to imply otherwise.

Be aware too that every stone in this collection measures within a few points of every other for brightness and saturation. The differences between them are pattern, not colour.

Wearing it

Twenty-five carats suits a pendant or a bold ring for careful wear. Malachite at 3.5 to 4 on the Mohs scale scratches very easily, so a bezel and a little care go a long way.

Care

No ultrasonic cleaner, no heat, no acids. Dry soft cloth. Keep it apart from harder stones in storage — a sapphire sitting next to it in a box will mark it.

We have not had this stone tested, so its treatment is recorded as "not tested" rather than untreated. Message +92 308 887 3888 for closer photographs. The rest of the range is in the malachite category.

Cash on Delivery is available across Pakistan, so you inspect the stone before paying, and returns are accepted within 7 days of delivery.

This particular stone

This listing is one natural malachite with a weight of 25.55 Carat. Its price is Rs. 3,530 — roughly Rs. 138 for each carat. Treatment: treatment not tested. Quote reference GS-000312 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 malachite rates 3.5 to 4. 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 malachite 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 malachite 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request.
