An opal's beauty is unique and arises from the amazing "play of spectral colours" in the gemstone. This originates from the breaking up of white light due to the three dimensional spherical shaped microstructure of the silica particles. This forms precious opal and can only be seen with an electron microscope. A similar phenomena of colour play is observed in a rainbow.

Natural opal is divided into three major categories - all opals, boulder and matrix opal. Each of these categories is described by their lightness or darkness (body tone).
