LUSTER
The word luster traces its origins back to the Latin word lux, meaning "light", and generally  implies radiance, gloss, or brilliance.The unique lustre of pearls depends upon the reflection  and refraction of light from its translucent layers and this is finer in proportion as the layers  are thinner and more numerous. The iridescence that some pearls display is caused by an  overlapping of successive layers - this breaks up light falling on its surface.
