Malachite is an alteration product of copper-containing carbon salts, often used as a companion to copper ore. Its hardness is 3.5-4, it is opaque dark green, and has a stripe pattern of color shades - this unique beauty is not found in any other gem, so there is almost no counterfeit.
Distinguish between malachite and turquoise
According to a series of features of malachite, it can be distinguished from other gemstones. Similar to it is mainly turquoise. However, the turquoise color is mainly blue with green color, the density is smaller than malachite, and the hardness is larger than that of malachite. The green strips of glass are also used to counterfeit malachite. The main difference is that the stripe of the glass is short and the width is unstable. The glass does not see silky luster, shell-like fracture, and there may be bubbles inside the glass, and the density is less than that of malachite.
