Malachite

Malachite is a green copper carbonate that forms in the weathered upper parts of copper deposits. It usually grows as rounded, bubbly masses built up layer by layer, which is why cut malachite shows its famous light and dark green bands and rings. It is soft and heavy, cut into , beads, boxes and carvings rather than faceted, and was ground for green eye paint in ancient Egypt. It is not grown in labs; imitations are printed or dyed resin and reconstituted powder.

Real malachite is heavy and cold, and its bands are irregular rings that follow the way the stone grew, with no two beads alike. A strand of identical beads with repeating stripes, or a bead that feels light and warm, is resin. Look in drill holes: real malachite stays green and banded right through.

Treatments. Malachite is often stabilised with wax or resin to improve its polish and fill tiny pores, and much cheap malachite jewellery is reconstituted from powder. Keep it away from heat, acids, ammonia and perfume, which dull it. It is a copper mineral: cutters work it wet because the dust should not be breathed, and it should not be soaked in drinking water. Clean it with a soft dry cloth. All gem treatments explained.

  • Malachite: Copperbelt, Zambia. Across the border from Katanga, on the same great copper belt.
  • Malachite: Gumeshevsky mine, Ural Mountains, Russia. Historic source of the Ural malachite used in the Malachite Room of the Winter Palace.
  • Malachite: Tsumeb, Namibia. Fine malachite, often with azurite.
  • Malachite: Milpillas, Sonora, Mexico. Botryoidal malachite and azurite.

How it is cut

Lab malachite is mostly machine-cut in calibrated sizes, which is why a cut lab stone costs little more than its rough. Fine mined stones are often native-cut to keep weight, then recut by precision cutters. See cuts from easiest to hardest and whether cutting your own is cheaper than buying cut.

Your kit for malachite

Five tools that let you check what you bought (a loupe, a UV torch, locking tweezers, a gem box and a pocket scale), plus a turntable that spins your stone under the light the way jewellers show one. The full collector's kit.

In short

Malachite grows over millions of years in the earth, or in hours to months in a lab. Both are real malachite; the mined stone is rare and priced for rarity, the lab stone is priced for the cost of growing it. Buy lab to wear and enjoy, check the listing names the mineral, and test it when it arrives.

Frequently Asked Questions

How can I tell if malachite is real?

Real malachite is heavy and cold, and its bands are irregular rings and stripes that are different on every piece. Fakes are lighter, feel warm like plastic, and often have repeating or printed-looking bands.

Is malachite toxic?

Wearing polished malachite is fine. The risk is the dust: cutters grind it wet and avoid breathing it. Do not put malachite in drinking water or make elixirs with it.

Why does malachite have bands?

It grows in layers inside cavities in copper ore, building rounded, bubbly masses. Each layer is a slightly different shade of green, so cutting through the mass shows rings and stripes.

What is the Malachite Room?

A hall in the Winter Palace in St Petersburg, now part of the Hermitage, decorated in the 1830s with columns and vases veneered in Russian malachite from the Urals.
