(the studs are for those who do not have ear holes) Pearl Treatment(1)
Pearl treatment is one of the steps to process pearls before they are put on the market. So how to treat it is very important. While pearl is more often than not a product from nature, it is difficult to control every pearl are as beautiful and colorful as our expectation, therefore, people will use some effective method to change or modify the appearance of pearls. After this, the most charming sides of pearls can show to us. This is very similar to the process of a jeweler cutting a raw diamond rocket to get a perfect diamond. Now, let’s look pearl treatments in the follow: 1. Polishing This process is applied to remove some surface blemishes and then increase luster. 2. Bleaching This process can make pearl’s color more well-proportioned. Lighten (make whiter) or alter color from dark to light, color by means of chemical and/ or physical agents or light. 3. Coating Good-quality pearls needn’t have to be coated to look lustrous. Spread an artificial layer of substance over the pearl surface to change pearls color or improve pearl luster. 4. Buffing Remove organic residues from the surfaces of natural. 5. Filling If a pearl is partially hollow or has a loose nucleus, we should fill the void with an epoxy substance. It can make the pearls more solid and also help improving their durability. Fillings can be detected with x-radiographs. 6. Oiling Oiling is used to improve pearl luster. 7. Irradiation
When light color pearls are bombarded with gamma rays, the irradiated pearls will achieve an iridescent bluish or greenish gray color. This method work suit for freshwater pearls and can be used with dyeing. 8. Dyeing Dyeing is often used method to get colorful pearls that meets people's different needs. Dyed pearls are not fakes, but people can get them much easier than pearls of natural color. For their soared price, few people can afford natural black or golden pearl, treated pearl is unquestionably a great invention to fit different trends. |
