A distinction reserved for pearls is that they are the only organic gemstones in the world. Pearls are mother nature’s inimitable gift to humanity. Typically formed under the sea by shellfish like oysters when an irritant gets fixed at the inner layer of mollusc shells, a pearl is difficult to come by. The respective mollusc then forms layers of calcium carbonate around said irritant, giving birth to a pearl over time. The modern age has witnessed the creation of cultured pearls, using a fine nacre covering that is capable of that unique pearly sheen.
