1. Malachite: malachite is produced in Zambia, Australia, Namibia, Russia, the Democratic Republic of the Congo, the United States and other regions in the world. China is mainly produced in Yangchun, Guangdong, Huangshi, Hubei and northwest Jiangxi. Malachite is a green basic copper carbonate produced on the surface of copper oxidized by moisture in the air, or a processed product of bran green (that is, basic copper carbonate) and cooked gypsum mixed with water and pressed into a flat block and natural malachite.

2. Turquoise: China is one of the main producing countries of turquoise. Turquoise is produced in Zhushan County of Hubei Province, Yunxi County, Maanshan Mountain of Anhui Province, Baihe of Shaanxi Province, Xichuan of Henan Province, Hami and Wulan of Qinghai, among which the high quality turquoise from Yunxian County, Yunxi County and Zhushan area of Hubei Province is famous in the world. In Iran, a famous turquoise producing area abroad, it produces the best quality porcelain pine and wire pine, which is called Persian turquoise. In addition, turquoise is produced in Egypt, the United States, Mexico, Afghanistan, India and the former Soviet Union.

The difference of composition between malachite and turquoise

1. Malachite: malachite is a carbonate mineral containing copper, with chemical composition of Cu2 (OH) 2CO3, CuO71.9%, CO219.9%, H2O8.15%, green, malachite green, dark green, etc., seemingly transparent to opaque.

2. Turquoise: turquoise is a collection of phosphate minerals of copper and aluminum, characterized by opaque blue, but also light blue, blue-green, green, light green, yellowish green, grayish green, pale white and so on.

Hardness difference between malachite and turquoise

1. Malachite: malachite belongs to monoclinic system, and its crystal shape is columnar or needle-shaped, usually cryptocrystalline stalactite, massive, crustal, tuberculous and fibrous aggregates, with concentric layered and fiber-like structure, hardness 3.5-4.5, density 3.54-4.1, brittle, shell-shaped to stagger fracture, reacts with hydrochloric acid and is easy to dissolve.

2. Turquoise: turquoise ground is not very uniform, the color is dark and light, and even contains light stripes, spots and brown-black iron wire, the density is also quite different, the porosity is loose, the less is dense and hard, the general hardness is 5: 6, the density is 2.6: 2.9, the refractive index is about 1.62, light green to blue fluorescence can be emitted under long-wave ultraviolet light.

The difference between malachite and turquoise

1. Malachite: there is also natural copper in malachite, which can activate the natural antioxidant enzymes in the skin, so that the antioxidant enzymes in the skin play the greatest role and achieve the purpose of antioxidation. The ancient Egyptians used to grind malachite into powder and apply it to festering wounds to achieve healing. French scientists have extracted a natural active substance from malachite, which is extremely safe and can improve the natural resistance of cells, remove residual impurities in cells, and thus enhance cell activity.

2. Turquoise: turquoise contains a variety of trace elements needed by the human body. long-term wearing of turquoise can promote cell regeneration, enhance immunity, strengthen the body, and has magical effects such as dispelling diseases, stabilizing emotions and increasing brain reaction. long-term wearing turquoise has the special effects of clearing heat, anti-inflammation, calming and lowering blood pressure, especially for the maintenance of bile.
