According to Pliny, the Nunnery of the Senate has a very beautiful opal. He is very fond of it. At that time, the ruler Anthony asked him to give it, otherwise he would be exiled. As a result, Nonining chose to go exile and refused to offer Opal to Anthony. The charm of Opal is evident. However, there are many varieties of opal stones, and the anti-counterfeiting technology is increasing day by day. Many consumers are helpless. Let's take a look at what classifications of opal stones are and what their fraud treatments are. Opal stone treatment In general, there are four main methods for the treatment of Opal fraud: 1, flatten Flattening is the most common method of processing opal. This is because the opal is formed in the deposit, the thickness is relatively thin, and it cannot be carved. Therefore, it is glued together with chalcedony or inferior opal. Quartz or glass reinforcement is enough. 2, injection molding Some opal qualities are poor and the surface is porous. In order to improve the quality, injection molding in the hole, cover the cracks, make it color change and enhance the level. The opal transparency after this treatment is high, and the hot needle is used to burn, and there is a plastic smell. 3, oil injection As with injection molding, in order to cover the pores and cracks and cracks of the inferior opal surface, it is then waxed and polished to enhance the gloss. After this opal hot needle is burned, oil or wax will flow out. 4, smoke and sugar water carbonization Smoke is used to blacken some opal stains that are not obvious, and enhance the color change effect. The operation is very simple, as long as the opal paper is hugged, and then wrapped with foil and heated, the effect can be achieved. But this opal only has a blackened surface and there is no change inside. If the sugar water is carbonized, the opal is firstly soaked in sugar water, and then taken out to dry and immersed in concentrated sulfuric acid, so that the sugar can be carbonized to achieve the dyeing effect. Which varieties are divided into Opal? Opal's variety is divided into a variety of programs, the common is to divide according to the number of body color and color change. According to body color opal, it is divided into black opal, white opal, fire opal, and water opal. According to the color change color, it can be divided into single color, three color, multicolored, colorful and other varieties. The more the number of color changes in Opal, the greater the intensity of the color change and the higher the value. Opal is unique, just like different people. The gorgeous red color is the most valuable in the black body tone, but maybe you like blue, so why not choose a beautiful blue opal? Red is the most expensive, then orange, yellow, green, Blue. The dazzling opal is the best, not too much attention to the color and body tone it presents.
