Natural and artificial synthetic crystals
The difference between natural crystal and synthetic crystal is also characterized by crystal luster. The surface of natural crystal jewelry exhibits oily luster, but the synthetic crystal jewelry table presents a glass luster, and no synthetic luster crystal is seen. ---Crystal Information
Crystal, though not a precious gem, is more and more liked by men, women, children and adults all over the world for its unparalleled medical effects and low prices. As a crystal lover, he hopes to have all kinds of crystals, natural or synthetic, but he certainly wants to know if his crystal is synthetic or natural.
The colorless crystal necklaces and chalcedony necklaces on the market today can be described as being blended with natural and synthetic materials, while colored crystal necklaces are mostly synthetic crystals. The real natural color is less, and even less is used to make a necklace.
The most prominent feature of synthetic crystals is that they have daughter crystal nuclei. The crystal nucleus of the synthetic crystal is better judged because the crystal and the generally long colorless column form a clear boundary with the surrounding synthetic crystals. However, some colorless synthetic crystals on the market today are colorless due to nucleation and synthesis. In addition, there are some natural inclusion features in the crystal nucleus or some bubbles between the crystal nucleus and the synthetic crystal, making some experienced People can easily mistaken for natural crystals. After careful observation, they will find out what kind of inclusions exist only in the child and in the Lord. There is a feeling surrounded by an intangible wall that cuts off without delay. The bubbles between the crystal nuclei and the synthetic crystals are distributed along the walls of the crystal nuclei, forming mutually parallel “bubble wallsâ€. Some air bubbles are squatting and the heads are arranged outward toward the end of the wall. In natural crystals, there are often clusters arranged along one surface, but this surface is often a single, fluctuating one, and the inclusions that make up the surface will be found as two-item inclusions under a gem microscope. Not just bubbles. The difference between the two is still obvious.
The second feature of synthetic crystals, especially colored synthetic crystals, is the uniformity of smoke. The color of the entire necklace is relatively uniform, especially the yellow crystal series and brown, black synthetic crystal. Natural yellow and brown, black crystal colors are often not uniform. Natural crystals are not only color uneven, but often tea color (except for the brown crystal), more interesting is that under the white light at night, tea yellow crystal without a little yellow, completely like brown crystal, if mixed with tea crystal It's easy to identify. The color of the synthetic citrine seen by the author is very pure and homogenous. There are individual shades that are darker but do not have tea shades and do not change color at night under white light.
It is worth noting that in synthetic amethyst, there are often some well-oriented dark purple slices, which are easily reminiscent of the characteristics of irregular flaky chromophores in natural amethyst. The biggest difference between the two is that the deep purple chromophores in the synthetic amethyst are arranged parallel to each other in a sheet-like orientation. The difference in size and shape is not obvious. The deep purple film is likened to a floating “violet cloth pieceâ€. The purple group can be seen as a floating "purple smoke group." This is the main difference between the two.
Natural colored crystals, especially amethyst, are also characterized by a sapphire-like hexagonal ribbon. What is interesting to note is that, in some synthetic green crystals, parallel ribbons often appear, and the ribbons develop parallel to the crystal nuclei more than one layer. I have also seen a series of synthetic green crystal necklaces, yellow and green appear in the country, much like the ribbon of natural crystals, plus some brown translucent solid impurities inside, easily mistaken for natural green crystals, but the formation of synthetic crystals The ribbons are distributed parallel to the daughter nucleus wall, straight, and the angle between the objects is the same. The whole crystal ribbon formed by the necklace changes in the same way. The color bandwidth of each grain is the same, giving people an “unity of paceâ€. Unnatural feeling.
The third feature of synthetic crystals is clean and flawless. Natural crystals often contain inclusions and sponges, while synthetic crystals are crystal clear. Individual synthetic crystals have bubbles or some solid impurities. In recent synthetic crystals, there are often triangular long tubular pores in which there are greenish red powders. This kind of long tube is characterized by being arranged in parallel along one direction, with a triangular section. There are often uneven green fire red powders distributed along the wall, the middle is often empty, and the long tube ends have a tendency to become sharp. The true natural hair crystal is a crystal containing minerals such as tourmaline, actinolite, rutile, etc. These minerals have a gas crystal form, such as the "bamboo-like" form of the actinolite. They are encased in crystals, arranged in a non-directional manner, and are thick, slender, and short-named, often accompanied by natural inclusions and sponges of natural crystals.
