About Mother of Pearl

El nácar es la capa interior irisada de las conchas de ciertos moluscos —ostras, mejillones de agua dulce y caracolas de abulón— compuesta por capas microscópicas alternas de aragonito y conquiolina que producen el característico brillo tornasolado por interferencia de la luz. Ha sido valorado en todas las culturas del mundo durante milenios para la fabricación de botones, incrustaciones, joyería y objetos decorativos. Las mejores fuentes de nácar comercial son los mares del Pacífico Sur, el Océano Índico y los ríos de agua dulce de Europa y América del Norte.
