Adular/moonstone is today one of the most precious gems, thanks to a unique appearance that is best described as a luminous foggy moon. Gemologists call this phenomenon adularescence. This gentle fluorescence of the stone is caused by the small inclusions of various metals and chemical compounds with different refractive indices. Individual layers of inclusions and incident rays create the impression of colors and lights as if they were coming from within the gem.
In addition to the famous Swiss mines, lunar stones are also collected in Sri Lanka or India. Monthly stones from Sri Lanka have the most beautiful colorful luminous inclusions and are among the most precious varieties of this gem. In India, interesting rainbow lunar stones with the inclusion of a whole spectrum of colors are found.
