The highest purity handmade Fibrous Malachite from Congo, gives a unique brilliant green hue. In this form, the pigment is brighter than the one that comes from malachite rocks.
The pigment is prepared by careful selection, grinding, washing, and levigation in controlled environmental conditions by an innovative approach. Coarsely ground fibrous malachite gives a deep brilliant green color while finely ground particles give a lighter more transparent tone.
