The forms of malachite and chrysocolla secretions in nature are extremely diverse.
The manifestation of a pseudomorphic crust of a bright blue chrysocolla on the surface of malachite aggregates is always a very beautiful, fascinating picture of natural natural formations.
The bluish-blue color of chrysocolla can also turn into a darker shade, due to this phenomenon-the presence of iron and copper oxides.
When the saturation of copper-containing solutions changes, the newly emerging layers often have a color of different saturation. If in the process of growth, the concentration of solutions often changed, the so-called ribbon or patterned malachite is formed, in which growth bands clearly appear.

Chrysocolla and malachite are very difficult in handling because of the porous, often heterogeneous structures - varieties of hard polished. The pattern of the stone is explained by its heterogeneous density. The light areas in malachite is more porous, and dark lines of pores between the fibrous crystals are virtually absent, so these layers of rock better polished.

Despite all the difficulties, the masters skillfully bring the polishing of this unique stone to a silky shine...which shows even more clearly all the fascinating bright game with patterned outlines and pictures..
