Nacre is the shimmering, iridescent layer found inside certain shells, like those of nautiluses and oysters, that creates the lustrous appearance we call mother-of-pearl. It matters because its unique combination of strength and beauty has made it valuable for both decorative objects and as a subject of scientific study for understanding natural materials.

珍珠母﹙Nacre或稱Mother of Pearl﹚ 是一種由軟體動物所產生的有機及無機混合物,做為該動物貝殼的內層物質;它也是構成珍珠表層亮麗的材料,材質非常堅固,但有彈性,且具有多種鮮豔色彩。 珍珠母材質一般存在於珍珠的外層以及珍珠牡蠣或淡水珍珠軟體動物的貝殼內層;許多其他軟體動物的貝殼內層也都含有珍珠母,例如海中腹足類動物之鮑螺屬、鐘螺屬﹙Trochidae﹚及蠑螺屬﹙Turbinidae﹚。
