Malachite is an ancient jade material. The English name of malachite is Malachite, derived from the Greek word Mallach, which means “green”.
In ancient China, malachite was called “green green”, “stone green” or “green Flanagan”. Malachite has such a beautiful name because of its color resembling the green spots on peacock feathers. Malachite is produced in the oxidation zone of copper sulfide deposits and is often symbiosis with other copper-bearing minerals (azurite, chalcocite, cuprite, natural copper, etc.). World-famous production areas include Zambia, Australia, Namibia, Russia, Zaire, and the United States. China is mainly produced in Yangchun, Guangdong, Huangshi, Hubei, and Northwest Jiangxi.
Brief introduction of malachite
The English name of malachite is Malachite, derived from the Greek word Mallach, which means “green”. Malachite has such a beautiful name because of its color resembling the green spots on peacock feathers. In ancient China, malachite was called “green green”, “stone green” or “green Flanagan”. Malachite is an ancient jade material. Malachite is a copper-containing carbonate mineral. Its chemical composition is Cu2(OH)2CO3, CuO71.9%, CO219.9%, H2O8.15%.
Main ingredients of natural malachite
Malachite is a carbonate mineral containing copper. Its chemical composition is Cu2(OH)2CO3, CuO 71.9%, CO2 19.9%, H2O 8.15%. It belongs to the monoclinic system. The crystal shape is often columnar or needle-like, very rare, usually in the form of cryptocrystalline stalactite, block, crust, nodules, and fibrous aggregates. It has a concentric layered and radial fiber structure. There is green, malachite green, dark green, and so on. It often has stripes, silky luster, or glassy luster, and seems transparent to opaque. The refractive index is 1.66-1.91, the birefringence is 0.25, and the pleochroism is colorless-yellow-green-dark green. Hardness 3.5-4.5, density 3.54-4.1g/cm3. It is brittle in nature, with a conchoidal to uneven fracture. It reacts with hydrochloric acid and is easily dissolved.
The main origin of malachite
Malachite has such a beautiful name because of its color resembling the green spots on peacock feathers, and it is purified. In ancient China, malachite was called “green”, “stone green” or “Qinglanggan. Malachite is produced in the oxidation zone of copper sulfide deposits, and it often coexists with other copper-bearing minerals (azurite, chalcocite, red Copper mines, natural copper, etc.). The world’s famous production areas are Zambia, Australia, Namibia, Russia, Congo (Kingdom, the United States, and other regions. China is mainly produced in Yangchun, Guangdong, Huangshi, Hubei, and northwestern Jiangxi.
Disadvantages and maintenance of malachite
Maintenance of malachite. Malachite is not durable as a gemstone, has low hardness, and cannot maintain good luster for a long time. It can only be used as beads and brooches. The Russians used malachite as a material for interior decoration of buildings, and the large columns of St. Isaac’s Cathedral in Leningrad were inlaid with malachite. Malachite is also used for carving various worship supplies and decorations, fireplaces, and tabletop inlays.
Malachite is a supergene copper mineral. Because of its high copper content, it is green or dark green. It was also called “stone green” in ancient times. According to the “Compendium of Materia Medica”: “The Shilusheng copper pit is the ancestor of copper. Copper is green because of the purple sun. The green is long and becomes stone, which is called stone green.” Because of its color and its unique concentric circular shape. The pattern is like the beautiful tail feathers of a peacock, hence the name, and it is especially precious.
Varieties and evaluation of malachite
Malachite is used as an ornamental stone and craft ornamental. It is required to have bright colors, pure and uniform, clear ribbon patterns, and dense blocks without holes. The bigger the better. Malachite opal requires a positive background color and a clear light band. Malachite can be carved into heart pendants, egg-shaped ring faces, necklaces, and can be made into seal materials.
Why is malachite so popular?
Malachite is an alteration product of copper-containing carbon salt and is often used as a co-product of copper ore. It has a hardness of 3.5-4, an opaque dark green, and a striped pattern with shades of color-this unique beauty is not available in any other gemstone, so there are almost no imitations.
Distinguish malachite from turquoise: Malachite can be distinguished from other gems based on a series of characteristics. It is mainly similar to turquoise. However, the color of turquoise is mainly blue and green, the density is less than that of malachite, and the hardness is greater than that of malachite.
Green-striped glass can also be used to imitate malachite. The main difference is that the glass has short stripes and unstable width. The glass does not see silky luster and conchoidal fractures, and there may be bubbles in the glass with a density less than malachite.
Malachite is produced in Russia, Romania, Brazil, and so on. China’s malachite origin is mainly in Hubei.
The word “malachite” has the meaning of “wife happiness”. Natural malachite presents a strong green and emerald green luster. Although it does not have the brilliance of jewelry, it is a noble stone with a unique elegance. Malachite has many mysterious legends. As early as thousands of years ago, the ancient Egyptians once called it the “sacred stone” and believed that it had the effect of repelling evil, so it was used as a talisman; in Germany, people believed that people wearing malachite could avoid the threat of death, In fact, fundamentally speaking, it is also the role of amulets. In ancient my country, malachite was made into various kinds of jewelry to wear, but because of its high price, ordinary people have no chance to wear it.
The effect of natural malachite on people
anti-oxidation. There is also natural copper in malachite, which can activate the natural antioxidant enzymes (SOD) in the skin so that the antioxidant enzymes in the skin can play a maximum role and achieve the purpose of anti-oxidation. Wearing malachite jewelry can slow down the formation of the skin’s stratum corneum, thus achieving the effect of delicate and tender skin.
Disinfect and regenerate, decompose, and grow new. The ancient Egyptians used to grind malachite into powder and apply it to the festering wound to achieve healing. Therefore, wearing malachite jewelry can absorb the natural energy contained in malachite and absorb external radiation to reduce skin irritation.
French scientists once extracted a natural active substance from malachite. This material is extremely safe, can improve the natural resistance of cells, remove residual impurities in the cells, thereby enhancing cell viability. Moreover, this malachite extract is green, safe, and does not cause any burden on the skin. So this is also the fundamental reason why modern people are keen on malachite jewelry, which is naturally harmless.
After scientific identification, all well-known cosmetics on the market contain trace copper elements with the same atomic structure as the copper in malachite. Because of its anti-oxidant and anti-aging effects, skincare products such as malachite extract have even appeared.
