Man-Made Jewelry Malachite
V. S. Balitsky, T. M. Bublikova, S. L. Sorokina, L. V. Balitskaya, and A. S. Shteinberg


Jewelry-quality synthetic malachite is now being manufactured in the USSR. The texture, structure, and physical and physico-chemical properties of this synthetic malachite are reported. Three textural types have been identified: banded, silky, and bud-like. The malachite is composed of closely adjacent spherulitic aggregates, the generation and growth of which are controlled by the crystallization conditions. In chemistry, color, density, hardness, optical properties, and X-ray diffraction, the synthetic malachite proved virtually identical to the natural material. Only in the thermograms were significant differences noted. Therefore, the man-made malachite holds much promise for use in stone cutting and the jewelry trade.
