Fashion in some parts of the Orient suggests that certain colours of clothing and jeweilery be worn on different days of the week. As the most interesting gems to the Easterners are those exhibiting phenomenal qualities such as asterisms (luminosity in the form of a star from reflected light) or chato-yancy (iridescent luminosity producing a thin bright line), the stones for days of the week include these features.
