Description

THERE'Opale Etiope, like all the opals, is amorphus, i.e. without an ordered crystalline structure. The training of the opal takes place through a slow deposition of a colloidal silica gel that, depending on the environment of deposition and formation, can enrich with traces of other mineral substances.

The type color game of the opal Ethiopian is an optical effect caused by the diffraction of light when it interacts with its internal structure. It is an optical phenomenon that happens when the luminous waves are deviated from objects that have dimensions comparable to their wavelength.
