Malachite is a common gemstone from the mineral class of carbonates and nitrates. Its beautiful colors and grains make it a very popular gemstone.
Pillars in Moscow made entirely of Malachite are extremely impressive. Dye manufacturers use Malachite as an ingredient in their dyes.
Malachite comes exclusively in green shades and these can range from pale to dark green, but the most striking feature of this stone is its intricate grain that looks like wood grain and shows all sorts of different greens.
Although this gemstone is quite common, it is relatively expensive because processing it releases poisons in the dust and grinding water, which makes production very expensive.
