"Natural green crystal", if someone sells it in the market, you don't have to look at it. It must be fake (there are few real green crystals, and they are collected by famous artists). Of course, there are green rabbit hair and green hair crystals, but they are not green crystals. The following are common fake green crystal clusters on the market, also called terbium-plated crystals.
"Natural Red Crystal" is red and beautiful. Don't be cheated. Most of them are molten crystals. There are natural red crystals, but less than pandas. Crystals wrapped in red minerals are still common (red rabbit hair, burnt crystals, etc. ) but the crystal itself is not red.
Friends who play "Natural Blue Crystal" online games must know that Blue Crystal! ! ! Remember to buy crystals, not equipment. Rock crystal is not blue, aquamarine is blue, but it is a kind of beryl, not crystal. The most difficult "crystal cultivation" to identify, you will never think that it is so simple to distinguish the authenticity of a string of crystal bracelets. The possibility of glass, resin and synthetic crystal is ruled out, but the biggest problem is also the most difficult one-how to distinguish "crystal cultivation" from "crystal cultivation" is a headache for appraisal experts. Because its physical characteristics, composition and hardness are completely consistent with real crystal. The only difference is that the original stone cultivated by crystal has no hexagonal system, but it is difficult to identify after being made into bracelets. However, the biggest advantage and disadvantage of crystal cultivation is that it is too perfect. Hehe, I will talk about this later.
Second, the most practical identification method when purchasing (usually universal, but not absolute).
1, crystals mostly contain ice and cotton. In general, it can be determined that there are natural ice and cotton (of course, there are also synthetic and growing crystals, ice and cotton with added or changed colors, which are called optimization in the national quality supervision and appraisal certificate. This is more complicated, let's not talk about it now), and part of it is mineral deficiency. Buying crystals is a great challenge for perfectionists. In fact, you don't need to care about the imprint left by nature to buy crystals.
2, no cotton, no ice crack, the same color crystal, either the best or unnatural.
3. No matter whether the bracelet you buy is round, square or follow the model, there must always be eyes on the bracelet (for stringing), so let's start here. Hold the bracelet in your hand, carefully separate the two beads and carefully observe the holes inside. You should know that all the eyes (holes) on the beads of crystal bracelets are drilled by hand with semi-automatic equipment. As long as they are drilled, they must be big at one end and small at the other, so the holes at both ends of a bead should be the same-one is big and the other is small. Of course, it does not rule out that there is a technology of drilling holes at both ends. Even so, when we drill in, we will still find tiny cracks and flaws on it, which can't be avoided by any expert with the current technology. If the drill holes of the beads on your hand are very neat, and you can't see any cracks or flaws, it proves that they came down from the assembly line, and the possibility of glass is greater than 99%.
