A natural pearl that can be seen clearly under a gemological microscope is created by bivalve mollusks, primarily oysters, Ostreidae, but also freshwater mussels, and rarely by snails. The pearl is known as La Régente. These filter feeders suck in water and nutrients, along with occasional silt or sand sized grain called an irritant. The irritant may stick to the mantle and the outer skin of the mantle, the epithelium. Although pearl is not an inorganic mineral but rather the organic product of oysters, it is considered by many to be a precious gem. Pearls have been valued for their natural beauty, no faceting or polishing required, for some 6000 years. Pearl quality is determined according to shape, color, size, and luster. The pearl can be clearly seen using a gemological microscope. Spherical are the most valued, but many pearls are irregular shapes, which are termed baroque or barrel pearls. Extreme dryness or moisture are both damaging conditions for pearls, as well as acids, perspiration, cosmetics, and hair spray. The low hardness means pearl is easily scratched and therefore storage is an important consideration. (more…)
