If there is no minor variation, line, or no imperfection on the pearls, the price will be more different-much higher. Perfect pearls will be very expensive; otherwise, they are imitation pearls (not real). Our pearls grow in water and are special by nature, so it is normal for these freshwater pearls to have some minor imperfections. This difference can be a small line, mark, shape, or natural color variation. Due to minor size, shape, and color differences. Due to lighting, there may be slight differences between the photo and the real object. To judge the real or freshwater pearl compared to the fake or man-made pearl, you need to know there are four imitation pearls now on the market. One type is made of pearl-white concrete, a second one is glass, a third is plastic, and a fourth there are various pearl powders. Normally these imitation pearls are very round without any spots, lines, or imperfections. Some are easy to break, also often very cheap or imitation quality, and if you use a knife to scratch them the pearl skin can come off and the fake core of the pearl will come out. In addition to a scratch test, imperfection test, price test, and feel-cool quality test, there is a color test.
