Malachite is a copper-bearing carbonate mineral, named for its deep green color and layered banded patterns that run from dark to light, resembling peacock feathers. It usually forms in the oxidation zones of copper deposits and often occurs alongside minerals such as azurite; historically, it was also one of the important indicators people used when searching for copper ore.

Globally, malachite sources are concentrated in regions rich in copper resources. The Ural Mountains of Russia were once famous for producing large, high-quality malachite; the Democratic Republic of the Congo and Zambia in Africa are currently important producing areas; in addition, deposits are also distributed in Australia, Namibia, Mexico, and the U.S. state of Arizona, among other places.

In China, malachite is mainly produced in the copper mining areas of the south. The malachite found around Yangchun in Guangdong tends to be large in size with clear banding patterns, attracting considerable attention in the ornamental stone and collectors' fields; the Tonglushan area in Daye, Hubei, a copper mining area with a long history, also produces malachite, and copper mining sites in Jiangxi, Yunnan, and other places likewise yield occasional finds.

Malachite has a warm, smooth feel but is not very hard, and it is often made into bead strands, carvings, ring faces, and decorative objects; after being ground into powder, it can also be used as a green pigment. When selecting, those with vivid color, clear banded patterns, and dense structure are preferred. For daily wear or storage, avoid knocks, bumps, and scratches, keep it away from acidic substances and high-temperature environments, and when cleaning, gently wipe it with a soft cloth to maintain its luster.
