China is already the largest consumer market in the world. Some people have used their brains to pack some cheap things into special packaging and turn them into "high-end products" to make profits. Numerous people have been deceived by these "disguised" products. The following are typical examples. They are pulled out as a negative case to remind everyone.
Freshwater "Golden Pearl"
Pearl is one of the natural organic gemstones and is popular among women of all ages. Pearls are divided into freshwater pearls and seawater pearls. The most popular ones are Nanyang Jinzhu and Tahitian black pearls.
Nanyang Jinzhu
However, there is a freshwater gold pearl, the color is very beautiful, the price is also cheap (about a few thousand), compared to a string of tens of thousands or even hundreds of thousands of Nanyang gold pearls, it is really cost-effective. But if you know that it is "dyeing", would you still buy it?
Natural freshwater pearls are available in natural gold and black. If a merchant sells freshwater pearls, whether it is golden or malachite green, it must be dyed! The heads of gold beads and black beads are relatively large, basically 8mm or more, and very few are 8mm or less. If the pearls below 8mm, especially below 7mm, are the color of gold beads and black beads, it is seriously suspected to be dyed.

Natural gold beads are evenly distributed in color and are accompanied by beautiful smudges, while the color of dyed gold beads is slightly sluggish and rigid. Under the ten-fold magnifying glass, there is a clear color accumulation at the drilled hole of the dyed gold beads, that is, there is "spot" deposition.

Emperor stone
Emperor stone, this name sounds quite domineering. It belongs to the yellow wax stone, is a very cheap ore, and the color of the emerald stone is mostly gray. At present, 99% of the colorful emperor stone ornaments circulating on the market are artificially dyed, and the blue emperor stone is no exception.
From the color and the grain, the blue emperor stone is similar to the turquoise. Therefore, some unscrupulous merchants sell the blue emperor stone as a turquoise to a person who does not know how to do it.
