The colors of pearl

Observing pearl from different angles under the lamplight, we can find that pearl will emit mysterious colors and change as the angle changes. Some pearls, glittering and translucent, look like drops of drew scattered in lotus leaves in the early morning. And some are copper mold from thousands of history, primitive and mysterious. Why? To analyse the fantastic phenomenon, we should begin form pearls' structure and composition. There are two factors affected the colors of pearl: One, pigment secreted by pearl shell. Pigment varies with different environment and shellfish. As the environment conditions are kaleidoscopic, the colors of pearls certainly seems to be the question. The different pigment are the result of containing mental trace elements. The chemical composition of pearl are mainly calcium carbonate. It also contains a little keratin protein, moisture and trace metals. Among those, Pearl Beads containing copper are gold, while some with silver are cream. Pearls containing sodium are carnation, while pearls with zinc are pink. The pure pearls are white as jade. Two, the internal structure of pearl. The main component of pearl is bead-like or Spearhead shaped calcium carbonate, occupying 82-93%. They are vertically arranged in radial pattern in the layers of pearl, which plays a key role in the forming of pearls' rainbow luster. Pearl comprises a series of layers of 0.3-0.4 μm. The layers are parallel with concentric circles profiles. And every layer is very smooth and translucent. When light irradiated to the pearl, some of them will be reflected by pearl surface, but some will tramsmit into the internal part of pearl. They will be reflected partly, and others will penetrate into the deeper pearl layer. Thus, in every pearl layers, some light will be reflect, some will be refracted and some will go deeper. Pearls look like bright and shiny due to the light reflection, pearl is more glittering and transparent with transmission, and it emit rainbow luster owing to refraction. The color of pearl itself, the surronding colors and colors result from refraction make pearl more dreamy and hazy with mysterious verve. However, the beauty of pearl are far form its rare and the stories recorded by long history. Stories related to pearl emerge endless as real
