Mother of Pearl and pearls are similar, but not the same.
Mother of pearl, known as nacre, is a blend of minerals that are secreted by oysters and other mollusks and deposited inside their shells, coating and protecting them from parasites and foreign objects. It is strong, resilient, and iridescent.
Mother of pearl appears iridescent because the shell has a microscopically fractured surface which interferes with the wavelengths of visible light. This in turn produces different colours (called structured light) when viewed or illuminated from different angles. It is the same the effect that you see on soap bubbles.
Jewelry made from mother of pearl falls in the group referred to as organic jewelry — jewelry that originates from a living creature, plant or organism.
Mother of pearl is very lightweight making it an ideal choice for those who do not like heavy jewellery.
