Opal is an amorphous colloidal mineral (hydrated silica: SiO₂·nH₂O) without a reticular structure, semi-amorphous or microcrystalline, in fact it does not appear in crystals, but in veins, nodules and crusts of various colours, often with wonderful iridescence. The color varies from transparent to milky white, with an infinite number of different intermediates (green, red, yellow, brown, black). The water content can reach up to 20%. The formation of opal occurs through slow geological deposition of a colloidal silica gel at low temperature.

It includes many varieties including thecommon opal, thenoble opal, theblack opal, thewater opal, thefire opal, thexyloid opal and the hyalite.

The word opal It has a common root in Sanskrit ùpala, in Greek ὀπάλλιος opallios and in Latin opălus (with meaning of precious stone).

The bright red or orange variety is so called due to its bright color.

This variety lacks iridescence and, in the more valuable varieties, milkescence is also lacking, while the less valuable samples are more cloudy. The bright orange-red color is due to ferrous oxide. The cut is made in facets or on a curved surface.
