Mollusks are filter feeders, sucking water in with their valves, extracting minute food particles from the water then ejecting the water out. Their diet consists of ‘Phytoplankton’, microscopic algae, and these algae differ according to season. In the Gulf of California the blue-green algae called ‘Cyanophites’ are abundant in winter, but in summer a golden algae called ‘Diatoms’ are more common. These different ‘Phytoplanktons’ provide the mollusk with materials that change the color of their shell and nacre.

Some trace elements are acquired from the water, such as metallic ions, that help the Mother of Pearl gain its unique coloration. Iron can give a pink color, copper a green to blue hue, magnesium a yellow coloration etc.

The term ‘Iridescence’ is often appropriated to Mother of Pearls as well as to opal. Iridescence is a general expression used when describing the presence of a rainbow effect across the surface; this is produced by the interference or diffraction of light through the gems crystal structure.

Mother Of Pearl Care

Mother of Pearl is a hydrated gemstone, so it is essential to keep it away from direct sunlight, strong sources of heat or very dry atmospheres. If Mother of Pearl is left to dry out its surfaces crack and it becomes less resistant to ware and tear. Never use strong abrasives or alcohol to polish your Mother of Pearl, as this will destroy its play of color.
