designer_replica (Louis Vuitton)LV 4245 watch A number of factors affect the appraisal of pearl quality. We recommend that customers learn the basics of selecting fine pearls to make pearl buying an enjoyable experience and to ensure a sound investment. Pearls SizePearl size is mostly determined by two factors: the size of the implanted nucleus and the thickness of the nacre that grows layer upon layer around the nucleus. A large cultured pearl that lacks nacre thickness has a low value, and tends to discolor and crack fairly easily. A pearl with a thick nacre coating will retain its luster and beauty for a lifetime when properly cared for. For pearls of similar quality, the most important other determinant of price is the size of the pearl. The size is generally measured in millimeters. Pearls ShapePerfectly round cultured pearls are the rarest. Although most cultured pearls are nearly round, only about 1% is perfectly spherical. To check a strand for roundness, roll it across a flat su***ce. The strand should move evenly and smoothly. Pearls Luster Luster refers to the su***ce property that imbues cultured pearls with their shine and beauty. When checking pearls for luster, view them while standing with your back to a source of light. The sharper your reflection on the su***ce of the pearl, the higher is the luster and the better the quality. designer_replica (Louis Vuitton)LV 4245 watch ColorPearls come in a variety of shades, with the major classifications being white, pink, silver, cream, gold, and black. Choice pearls also have a secondary color, or ;overtone;, around the su***ce of the pearl. These overtones are usually rose, green or blue. The color should emanate from deep within the center of the pearl. All the pearls in a strand should be consistent in color. Pearls Su***ceJust as with any product of nature, all cultured pearls have minor imperfections. A quality cultured pearl is free of large pits or blemishes.
