|Nacre||Nacre thickness is an important factor when measuring a pearlʼs quality. Nacre is the coating that the oyster forms around pearls and that is composed of calcium carbonate crystals. A pearlʼs appearance helps determine its quality which has a lot to do with whether the nacre is thick or thin.|
