Opal: a stone that has always unleashed passions
As we have already indicated previously, the common opal does not benefit from the ability to produce a color scheme also called iridescence or lights. It can be monochrome or polychrome and present, unlike the noble Opal, graphics, drawings, patterns that are fixed. The cause of this immobility is its chemical composition, with no light diffraction effect. Indeed, common Opals do not have an arrangement of nanospherules of ordered and regular silica and diameter, similar to its counterpart the precious Opal. The colors are very varied: Colorless, white, orange, red, pink, green, blue, yellow, purple, multicolored ... They can contain many inclusions of iron oxides or micro-crystallizations of rock crystal etc ... They are usually opaque or translucent. These are stones which have known great variations in popularity through the eras, in turn adulated, then hated according to legends, rumors and beliefs. In any case, they have always aroused interest and have been talked about all the time. We will come back to this fact in the section dedicated to precious Opals.
