1. beeswax
The most common forgery is the use of synthetic resin and polyethylene.
Although in essence, beeswax is also formed by resin, human natural beeswax has gone through hundreds of millions of years of tempering, and the hard work paid is incomparable to synthetic resin.

The biggest difference between synthetic resin and natural beeswax is that its surface can often see flowing lines produced after heating and melting, and its feel is not as light as natural beeswax.
Let's talk about polyethylene first Maybe you don't know what polyethylene is. In fact, it is pure plastic. It is made of light and easy-to-dye plastic and is used to pass off as beeswax. But this just gives us a handle. We just need to put the beeswax in saturated salt water, so that the plastic will sink and the real beeswax will float. At the same time, you can use this method to test whether the beeswax in your hand is a fake.
2. Hetian jade
The most common fakes are quartzite jade and glass.
▲ Quartzite jade
Quartzite jade has a natural advantage in counterfeiting Hetian jade, because it has this genuine capital without treatment, let alone post-treatment, so how to distinguish it? In fact, under many contrasts, you will find that it just lacks the oily feeling of Hetian jade. Quartz jade is full of glass luster and crystal feeling because of its different structure, which is very different from "nephrite".
▲ emulsified glass
Besides, glass is the cheapest man-made material. Emulsified glass has the same problem as quartzite, that is, it lacks the oiliness of Hetian jade. And it is easy to see the bubbles in the glass, so as to distinguish between true and false.
3. Jade
The most common counterfeiting is using various other varieties of jadeite, Kethleen, quartzite jade and so on.
▲ Quartzite jade
There are too many substitutes to pretend to be jadeite. 90% are Dongling jade, water foam, jasper, quartzite jade and so on. They are similar in that they look like jadeite, green and close to jadeite, so they are really hard to prevent. The glass in the ice is even more unimaginable. The cost is extremely low. After being forged into bracelets and rings, they can sell tens of thousands. This kind of unconscionable money is really unimaginable.
4. Nanhong
The most common counterfeiting is ruby, agate, glue injection dyeing and so on.
▲ Mozambique agate
African material is an agate from Mozambique, Africa, which has glass luster and higher hardness than Nanhong. In terms of color, it is lighter red. The difference between Nanhong and African materials can be distinguished from their contents, vermilion points and transparency. The red part of African material is mostly in the middle of the original stone, which shows that African red agate is a transparent crystal wrapped in the red part. South red agate agate is a red part wrapped in transparent crystals, which is one of the characteristics that distinguish the two, even if it is made into a finished product.
▲ Red and green stone
A large number of red tourmalines are produced at the same time in the southern red production area of Liangshan, and the shell of one kind of volcanic red tourmaline is almost exactly the same as that of the southern red of Liangshan, so it is basically impossible to judge and identify it correctly from the appearance. Ruby is heavy, and its surface is dry and not wet. Use a flashlight that specializes in detecting jewelry and jade, and choose white strong light to resist grinding. Completely opaque is ruby. No matter how thick and fleshy the real south red agate is, there will be a little flash on the edge.
