Nacre (pronounced NAY-kur), quite simply, refers to what is more commonly known as mother of pearl. It is the precious material that forms the bulk of most pearls – that beautiful, strong, radiant substance that gives the pearl its beloved and enduring luster.
Scientifically, nacre is the inner iridescent layer of oyster shells which is composed primarily of aragonite (a form of crystalized calcium carbonate) and conchiolin. Conchiolin is a tough insoluble protein secreted by mollusks forming the shell within which calcium carbonate is deposited. An oyster, when creating a pearl, alternates brick-like layers of aragonite with a film made of organic material. According to Harvard University, that layered structure is why nacre is “a material of extraordinary strength.” 
A pearl forms inside an oyster by a natural process in which the oyster secretes layers of nacre that wrap around a foreign object, or, in the case of cultured pearls, a nucleus that has been inserted specifically for the purpose of cultivating a pearl. These layers produce the eventual thickness of nacre in the pearl. The more layers of nacre, the higher the luster of the pearl.  Or in other words, the thicker the nacre, the better the luster.
