Some varieties of chalcedony and quartz have similar optical effects, but despite this, they are just imitations and only mislead those who have never seen a real adularia. The unique iridescence in this mineral is due to its unique internal structure. Glitter creates a reflection of light from the inner structural layers. Thin layers of albite reflect an attractive blue color, while thicker layers of feldspar are white.

To get the most beautiful shine, silver or blue light, which seems to touch the surface barely and at the same time hides in the stone, its base must be parallel to the plane of alternating layers. Because of this, the gem is processed with a cabochon. Otherwise, the irisation can go unnoticed, which deprives the stone of all value. The most prized specimens with a strong blue glow, while without turbidity, inclusions and cracks, so are used for jewelry cutting. Also rare is rainbow moonstone iridescence, which exhibits other colors in the spectrum besides blue.
