1. Inclusion discrimination: Inclusion discrimination is to see whether there are natural phenomena such as ice cracks and clouds in tea crystals, because crystals are products of nature, and their existence is inevitable. If it is a synthetic tea crystal, it must be perfect. So it's very easy to distinguish.
2. Touch: Generally speaking, the temperature rise of crystal stone is slower than that of artificial crystal. Wearing it on the human body, natural tea crystals can finally reach the same temperature as the human body, but artificial tea crystals are higher than human body temperature, and natural tea crystals are very dry and delicate to the touch!
3. Send it to the appraisal institution: If you really want to make a quick and accurate appraisal, take it to the appraisal institution! Only charge a certain appraisal fee!
4. Plastic products: can be distinguished from the touch, temperature and hardness of hands.
5. Glass products: this kind is clear as water at first glance, has no texture, low hardness, single refractive index, mixed with bubbles, and is easy to distinguish, which can be distinguished by polarizer.
6. Melting crystal: mainland products are like glass, but most of them are made into spheres with the size of seven or eight centimeters to ten centimeters, which are very beautiful, but the refractive index is single and the hardness is low, which can be distinguished by polarizers.
7. crystal glass: it is actually lead glass. Glass products containing lead metal are the most popular in the market. Because of its good refractive index and dispersion rate, it is dazzling and dazzling. It is most suitable for decoration and decoration, but not for spiritual use. Generally, it can be distinguished by vision.
8. Artificial piezoelectric crystal: also known as crystal growth, the original stone has no hexagonal crystal system, which is the easiest place to judge; But if it is ground into a finished product, it is not easy to distinguish it by the above method. You need to use an ultraviolet spectrometer to distinguish between true and false. Of course, specialty store is easy to tell with the naked eye. The most common products on the market are colorless and transparent fake topaz, amethyst, amethyst and aquamarine crystal.
Ornamental value of tea crystal
Crystal is a crystal in which the internal constituent particles of silicon dioxide are arranged periodically and repeatedly in three-dimensional space. Crystal is as clean and transparent as water and as bright as glass. Crystal belongs to gem series, so the ornamental value of crystal is higher than ordinary ornamental stones, such as ordinary painted stones and pictographs. Compared with other gems, no gem crystal can be as big and clear as crystal, so the value of crystal ornamental stones cannot be simply compared with other gems or other ornamental stones.
First, the color beauty of crystal
There are many colors of crystals, such as amethyst, red crystal, white crystal, tea crystal, smoky crystal, black crystal and colorless crystal. Crystals can have many colors on the same crystal, such as colored inclusion crystals; Purple and white are mixed on a crystal; Hair crystals of various colors, etc. Under the sunlight, these crystals are sparkling and dazzling, as if it were a spectacular scene of "shooting the ground with nothing, spitting rosy clouds with treasure".
Second, crystals and various minerals are beautiful.
Some crystals naturally contain minerals of different colors, such as pyrite, mica, wolframite, cinnabar, tourmaline, fluorite and other minerals, forming different color combinations and different shapes, which are lovely, realistic and unforgettable. This ingenious and peculiar natural combination has an uncanny charm, which is simply incredible.
