The banding on this stone

A pale grey wedge occupies the upper-right. Running diagonally through the middle is a thick, solid dark-green band — the heaviest single band of any stone on this page. Bright green ripples crowd the left edge and the lower-centre, and a pale-green sweep closes the bottom-right corner.

The weight of that central band gives the stone a spine. Most malachite reads as layers of roughly similar thickness; this one has a clear dominant feature with everything else arranged around it.

The colour, measured

Saturation measures 57% from the photograph. Across this whole collection the figure sits between 56% and 59%, which tells you something useful: malachite's colour is remarkably consistent. It is always this green. What varies from stone to stone is the pattern, not the hue — so when you are choosing, choose on pattern.

That consistency is also one of the reasons malachite has been used as a pigment and an ornamental stone for thousands of years. You know what you are getting.

Wearing it

Just under 20 carats suits a pendant or a dress ring. Malachite is soft at 3.5 to 4 on the Mohs scale and will scratch easily, so a bezel and reasonable care are both worth it.

Care

No ultrasonic cleaner, no heat, no acids. Vinegar and lemon juice etch the surface. Dry soft cloth only.

This particular stone

This listing is one natural malachite with a weight of 19.6 Carat. Its price is Rs. 3,230 — roughly Rs. 165 for each carat. Treatment: treatment not tested. Quote reference GS-000318 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.
