More and more gemstones have entered thousands of households. At the same time, more and more people are considering buying genuine gems. But the market often has various traps that make it hard to prevent. So how do you avoid these pitfalls?
1, can not be greedy and cheap to beware of unlicensed vendors
On many roadsides and subways, there are sometimes small stalls with the original stones of “Baltic Amber†and “Fushun Mineâ€. The price is a few dollars. Many people think it is cheap and looks better. Impulse to buy, even on-site grinding. This or golden "Baltic amber rough", or the black-faced "Fushun Mine Raw Stone", usually a plastic imitation or a Coba resin, certainly cannot be compared to real amber in terms of price and texture. The price of amber has been rising all the time. It is impossible to make a large chunk of amber rough for a few dollars. Therefore, you must not bring trouble to yourself for the sake of being cheap.
Nowadays people like to wear bracelets, especially in summer, and more and more people buy bracelets. Of course, everyone wants to buy good quality and cheap. On the flyover, on the subway, and on the side of the road, there are always people selling various bracelets, and the price is quite cheap. But we must be careful, because these seemingly similar to all kinds of jewels and jade, and labeled "laminite", "garnet", "crystal", "beeswax" ... may be plastic or glass imitated. Plastics and glass can almost imitation of all gems, which is confusing for collectors who lack relevant knowledge. Therefore, we still have to buy the bracelets in the formal market. There is no guarantee for purchase on the roadside, even if we know that we can't defend our rights after buying fakes.
2, can not be a light taste, stop knowing how to know the fur
After learning a little bit of fur knowledge or technical terminology, many Tibetan friends began to pan for goods. They even forced their own theory to “check in†and bought a combination of Nanhong, which is similar to Baoshan Nanhong. This mentality is the most undesirable. With the price increase of tourmaline, many “come to buy†tourmaline, but friends who are not very familiar with tourmaline, it is easy to buy “tourmaline†which is imitation of crystal cracking, and this kind of “tourmaline†is usually surface crack. More, the color is infiltrated into the crack and is uneven, showing a "reticulated" structure, and the stained deposit can be seen.
Collecting a class of things, the necessary theoretical knowledge reserves are indispensable, but can not be tasted. If you can compare the actual objects more conveniently, of course, it is easier to figure out the combination of physical and theoretical. For a gem, there are many cases of fraud, similarity, etc., so it is necessary to have a comprehensive understanding and to grasp the characteristics of the gem. Sometimes sellers are convinced to persuade you to buy value-for-money things, and even to teach some simple identification methods. In many cases, we will have the feeling of “selling the price of a big jump, the opportunity is rareâ€. At this time, we need to think calmly. I bought back a bunch of useless things because of the impulsive impulse. Sellers are always smarter than buyers, and this sentence needs to be kept in mind and remind yourself.
3, can not only look at the appearance needs to remain sensible and doubtful
Many friends see a similar "old coral", they must start. If you look closely, you can see that the wearing time is not short, but you can't believe that all the old ones are true. In the organic gemstones, the attraction of corals The force is still very large, in addition to dyed sea bamboo, the cheap white coral, dyed marble, pink glass, Gilson synthetic coral, etc. have become the "replacement" of red coral. People who like corals must pay attention to their growth patterns when purchasing, and careful observation can avoid being fooled. There are also a lot of "old beeswax" that are baked with new wax, not the color that is produced after long wearing. Some turquoises that look like "porcelain" are actually made of rubber. In the process of purchasing, you must be sensible, and you must have a skeptical spirit. For extremely beautiful gems, you must further determine their color and purchase them.
4, can not blindly confidently find experts to check the talent
Many people have accumulated a lot of experience after a long time of collection in a certain category of collections. It is a good thing to have relevant experience, but sometimes experience will confuse your eyes. The experience we accumulate sometimes makes ourselves blindly confident and not skeptical about the gems that our eyes see as real goods. Nowadays, various methods of counterfeiting are emerging one after another. In some cases, similar jade is used to serve as a well-known breed. For example, the “Chuzhou Stone†often mentioned in the Shoushan Stone Market, in which the texture is slightly better, it is sold as Shoushan Shanbo, and many Shoushan Stone veterans are eye-catching. For friends with more collection knowledge, sometimes encounter uncertain gems, don't blindly draw conclusions, may wish to find an expert to look at the check, after instrument testing, expert Q & A, will certainly give a reliable The conclusion.
PVC is a polar amorphous polymer with strong force between molecules. It is a hard and brittle material with low impact strength. After adding the impact modifier, the elastomer particles of the impact modifier can reduce the total craze induced stress, and use the deformation and shear band of the particles themselves to prevent the craze from expanding and growing, absorb the impact energy introduced into the material, so as to achieve the purpose of impact resistance.
