Mother of pearl
Composed of microcrystals of aragonite agglomerated together thanks to a protein called conchyoline, the nacre is secreted by mollusks. Throughout their existence, mussels, oysters or abalone produce nacre. This stone is also composed of 3% water.
The nacre stone is distinguished by its blue, pink or yellow reflections. These change depending on the angle of observation. This is what gives this stone its charm. It is the different successive layers of crystals that create its iridescence. The most common colors of mother-of-pearl are silvery white or light pink.
