First of all, what is a pearl? Pearl stone - consists of oysters and mussels living in warm and temperate waters. The formation period is on average 10 years. Pearl formation begins when sand or another foreign substance enters the oyster shell. Oysters cover this substance with a substance called mother-of-pearl. This substance contains 92% calcium carbonate. If the foreign substance settles completely into the flesh, it forms a spherical pearl; if not, a hemispherical pearl forms. Properties of the Pearl Stone One of the biggest factors that determine the value of the pearl is the age of the oyster. Because the older the oyster, the bigger the pearl will be. The most common pearl colors are pink-cream and white, but rarely black pearls can also be found. However, since a real black pearl is very valuable and expensive, many imitations have been made. A dark shiny black pearl - very rare and quite expensive. Care and Cleaning of Pearl Stone: It is sufficient to use warm water and damp cloth or soil to clean Pearl.
