A mother-of-pearl button is a type of button that is obtained as a result of a number of professional processes of real mother-of-pearl shells extracted from rivers and seas in the far east. Since the genuine mother of pearl button is made of natural and real mother of pearl shells, the cost is slightly higher than other button models. As a matter of fact, the cost of mother-of-pearl shells in nature increases due to the difficulty of the extraction process and the complexity of logistics of these operations in the Far East.
