Mother of pearl, also called nacre, is an iridescent layer of material, which forms in the shell lining of many mollusks. Mollusks create mother of pearl lining, in order to protect themselves and insulate them from getting a bacterial infection. Mother of pearl is most commonly taken from the pearly lining inside of oysters and abalone. Many early cultures used mother of pearl extensively beautiful jewelry and it became highly prized due to its iridescent quality and was often seen as a sign of wealth in some cultures. From the modern women’s point of view, having a unique mother of pearl silver pendant provides an elegant alternative or addition to traditional pearls.
