How can I say a real pearl from a faux pearl?
Faux Pearl is generally understood as any kind of pearl that is made of something other than right Nacre, whether it is plastic, glass or resin. Faux pearl is not usually understood as a cultivated pearl, although it is not, strictly, natural pearl. Real or cultivated pearls can also be treated, either dyes or special coatings, and may come from various molluscs except oysters. There are several different ways to distinguish an artificial pearl from a real pearl, and even distinguish a cultivated pearl from real pearls, some of which are more effective than others.
The most common way tells the faux pearl from the real pearl is usually known as the teeth of the teeth. The prerequisite for the tooth test is that you wipe the pearl along the teeth, and if the pearl feels smoothly, it is an artificial pearl, while if it feels bold, it is a real pearl. It is a great sound test, theoretically, because it can do it at any time. The problem is that this is nun unreliable because many situations can causeA false positive answer where you can think that an artificial pearl is a real pearl.
The idea of a tooth test is simple and at first glance it seems to be a good idea. The real pearl consists of many different layers of Nacre, built around central irritating, and thus are irregularly shaped and have bumps that can be detected against the tooth. On the other hand, the faux pearl is usually machine plastic or glass, so it will be perfectly smooth. But there are many exceptions.
For one thing, many cultivated pearls, although in fact not an artificial pearl, it will have enough Nacre to feel smooth. Or it may have been dyed or treated, which fills irregularities and also feels smooth. On the other hand, the artificial pearl can be intentionally made with the irregularities felt more like a real pearl. So while the dental test can work for the distinction of the most demanding artificial pearlY from untreated natural pearls, it would be less likely to recognize the difference between a finely made artificial pearl and a coated sophisticated pearl.
To be sure whether the pearl is false or real, it usually must either destroy the pearl or have access to more advanced equipment. With multiple pearls, you can sacrifice and sliced to look at the layering inside. The real natural pearl will have countless layers of thin Nacre, the cultivated pearl will have a strong core of the pearl and a thin layer of Nacre, and the artificial pearl will have a core coated with a scaly fabric. Without the destruction of the pearl, the X -ray can be used to get an even better look in to determine all sorts of pearls, including its authenticity.
One of the simplest ways to distinguish the faux pearl from the real perlyvas teeth, but just looking at the pearl group. If you place a collection of pearls, such as those in the necklace, under bright light, the color and gloss of the pearl become much obvious. Natural pearls will have mild changes in colorOut and shine can be more intense, while artificial pearls will be almost identical in their color.
