In recent years, tourmalines have been sought after, and friends who have not touched the tourmaline may be deceived. Therefore, some products related to counterfeit tourmaline have also become popular in the past two years. Some of the craftsmanship is not bad, and there are similar feelings of colorfulness, which has led some friends to be deceived. The most common cause on the market is the "popcorn", and some people have given it a nickname "popcorn"! As the name suggests, the basic raw material of "Blood Flower Crystal" is to use low-priced white crystal. Today, the Jewelry class will teach you how to distinguish between popcorn and tourmaline. 1, look at the color The biggest feature of tourmaline is that it is full of colors and eye-catching, and the brightly colored tourmaline is a gem of people's enthusiasm. Therefore, the popcorn crystal also seizes this feature, using low-cost white crystal, after thermal expansion and contraction treatment, it produces more cracks in its crystal. Then use various colors of dye to infiltrate the color into the gap, so from a distance, the color of the popcorn crystal is very attractive, and from some angles it is somewhat "stunning", but you should be careful, for color Specially stunning Beads, pay more attention. The reason is very simple. If the tourmaline was not well known before, there are some good materials that are used to make beads, but now, don't think about it, this material has been done before. Therefore, everyone should pay special attention to the "Bixi" beads, which are particularly bright in color. It may be popcorn. Generally, there are very few dark beads in popcorn, but true tourmaline, which is at least half of the dark color, unless it is a high-priced item. If the crystal is transparent and the beads are directly larger, the price will be higher. 2, look at the size The size of the tourmaline's beads is one of the important factors in determining the price. For popcorn, because the price of white crystal is low, it is normal to have big beads. Think about it, a string of dollars or tens of dollars, a little You can sell hundreds or even thousands of products under processing, and any business will be heart-warming. However, in the market, the current large-diameter tourmaline beads are not cheap. In the current situation, the beads above 11mm are generally very valuable, so you see a string of 11 or more, and the colors are particularly beautiful. In addition, the price is especially incredible, then you have to be especially careful. 3, see the price Price is also an extremely important reference, and the first thing that counterfeits will make you feel excited about the price. Most people who know some market know that the price of tourmaline is directly related to color, crystal, size and so on. But if you don't understand the tourmaline, then you should be careful. This tuition fee can't be handed over. Some friends spend thousands of pieces to buy hundreds of pieces worthless. 4, look at the crystal In fact, there is no such thing as a "crystal" in the blast, because that is simply a fake, but for the sake of science, it is recommended that you carefully look at it. The crystals of popcorn are actually seriously damaged, so there are many artificial cracks in the inside, which can be distinguished by the naked eye. At the same time, because of the dyed color, you can pay special attention to the periphery of the crack. Please see the picture below, because Dyeing agent, so there will be a certain dispersion state at the end. The harmful effects of popcorn Warmly remind all friends not to spend money to buy this kind of thing, because it is actually not as strong and beautiful as a complete glass bead! We know that white crystal is harmless to the human body. The real harmful thing is its stain. If it is a genuine stain, it may cause less damage to the human body, but unscrupulous merchants will choose cheaper, high in heavy metals. The dye is cheaper, the second is easy to color, and the color is longer. This reminds me of the manufacturing process of some cheap jade bracelets. I remember that TV news has been broadcast. Its harm is immeasurable. Because the crystals of popcorn are damaged, the dye can easily ooze out from the gap, endangering human skin, especially children. Therefore, it does not matter whether it is cheap or not. What is important is the harm to the body. Please pay special attention to your friends.
