Pearls develop when layers of calcium carbonate (aragonite or calcite) are secreted around an irritant inside the mollusk, creating a lustrous, smooth surface prized in jewelry.\u003c\/p\u003e\n\u003cp data-start=\"467\" data-end=\"476\"\u003eFeatures:\u003c\/p\u003e\n\u003cul data-start=\"478\" data-end=\"1251\"\u003e\n\u003cli data-start=\"478\" data-end=\"646\"\u003e\n\u003cp data-start=\"480\" data-end=\"646\"\u003eFormation: Pearls form biologically within mollusks as a defense mechanism, building concentric layers of calcium carbonate combined with a protein called conchiolin.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"648\" data-end=\"788\"\u003e\n\u003cp data-start=\"650\" data-end=\"788\"\u003eComposition: Primarily composed of crystalline calcium carbonate in the form of aragonite or calcite, bound together by organic materials.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"790\" data-end=\"1003\"\u003e\n\u003cp data-start=\"792\" data-end=\"1003\"\u003eAppearance: Typically round or near-round, with a smooth, iridescent surface called nacre or mother-of-pearl.
