IV's crystal experts from the Crystal Museum of the East China Sea, about identifying natural crystals. At present, the most popular online is the so -called seven tricks. Is it practical?

In from the experts of the Crystal Museum of the East China Sea, although the seven appraisal methods are very organized and seemingly make sense. However, if you understand the crystal, this is not useful for you. If you do n’t understand the crystal, you do n’t detect any results according to this.

I first look at the first

a, see: During the formation of natural crystals, it is often affected by the environment. To a slight uniform and small horizontal or catkins. The fake crystals mostly use the residual crystal residue and glass residue melting, which is made of polishing and imitation of color. There is no uniform stripes and catkins.

It experts from the East China Sea Shengshi Crystal Museum commented:
1. Nowadays, there are many fake crystals on the market, and the varieties include glass high -lead glass artificial crystal plastic. However, no one will be stupid enough to melt it with crystal residue. During the production process of raw materials, two types of by -products are produced, one is the polished powder, and the other is the gravel of the lower foot. The line price, the smallest gravel 1kg20 to 100 yuan (based on variety), natural white crystals are generally 40 yuan 1kg. If the punching is done well, it is equivalent to more than 120 per kilogram. Besides, there is far from the high pureness of the quartz. In terms of cost, the possibility of using crystal fragmented pseudo crystals does not have profits.

So the crystal residue fakes first.

2. From the most common white crystal, the purity of the local white crystal of the East China Sea is the highest in the world. Impurities, even if the jewelry is simple, can see anything, so it cannot be regarded as a basis for whether it is a pseudo crystal. Therefore, this also shows that the judgment method of this article is unscientific.

3. Many pan -sense crystals are actually used as natural crystals, but many semi -gems contained in crystals, such as obsidian, agate, and tiger -eye stones, are at all. Therefore, this trick basically has no effect.

b: Tongue licking: Even in the hot summer, licking the natural crystal surface with the tongue, it also feels cold and cool. There is no cool feeling of false crystals.

It experts from the Crystal Museum of the East China Sea said that there are three reasons here that cause it unscientific:
First, it is unsanitary. Natural crystal jewelry passes through the hands of many people. It is very unhygienic to lick with the tongue and is very uncivilized;
Secondly, only one time for a short time in the year is three volt -in heaven. How to lick at other times? So unscientific.
third, cold and cool feeling, then it feels like an uncertain thing. The same soup, I think hot may be just right. The same soup, 50 degrees is also hot, and 90 degrees is also hot. When you feel cool, it may be glass, because the glass is also cool.
Fourth, the crystal is only hot -guided, but it is very low than heat, so the temperature of the crystal in summer is usually consistent with the room temperature. Let you drink about 30 degrees of water in summer. You must not feel cool. The same is true of crystal. If you feel cool, it means that you are psychologically hinted by yourself or others. In other words, under normal circumstances, you don't have a cool feeling, but because of this psychological suggestion, you feel this psychological suggestion, so this article is also unscientific.

c, light: natural crystal is placed in the sun, no matter from which angle, it can release beautiful glory. Fake crystals cannot.

Ip experts from the Crystal Museum of the East China Sea said that this unscientific cause is:
1. Swarovski, Austrian crystal, etc. There are beautiful glory, let alone in the sun. This one cannot prove whether it is a natural crystal.
2. Why is it vertically? No provision requires that crystals must be carved in one direction. As for "no matter what angle", this is even more mysterious.

D, hardness: Natural crystal hardness is large, and it is gently drawn with gravel on the jewelry without leaving traces;

It experts of the East China Sea Shengshi Crystal Museum introduced this unscientific reasons:
The first crystal boss will not let you draw!
1. Jewelry appraisal uses standard hardness films, not simply finding something to draw conclusions. The gravel material is very unclear. The hardness of tiger eye stones and agate is much higher than the natural crystal. The hardness of the hardness is lower than that of glass. Therefore, if you don't consider the professional and unprofessional, you can draw N results if you change the stone.
2. The common imitation crystal jewelry is mainly high -lead glass artificial crystals. Artificial crystal hardness is equal to natural crystal hardness than high lead glass and ordinary glass. High -lead glass is higher than ordinary glass. The glass is higher than the iron, and the iron is higher than the plastic. According to this hardness order, if you draw ordinary glass, you can get some traces. Only acrylics are not traces, and the proportion of the stuff is low, and you don't know if it is not natural.
3. It is not conducive to jewelry maintenance. Natural crystals may have ice cracks during the formation. If the operation is not careful, it is easy to cause the crystal to disconnect from the ice crack. Even if there is no crack, because the crystal is low, it is easy to break.

e: Check it with a polarized mirror: Rotating 360 degrees under polarizing mirror is natural crystal with four dark and four dark changes.

If experts from the East China Sea Shengshi Crystal Museum introduced unscientific reasons:
1. The price of polarizing mirror is greater than the test cost, and the difficulty of buying is greater than the founding of the product technical supervision bureau.
2. No one uses it. None of the Crystal City in Donghai knows this prop, and few people will use it. The master of the Supervisory Bureau uses a high -power mirror. With experience, this is not necessary. In simple and highly difficult pure body crystals, such as white crystals, it is OK to use a high -power mirror or filter, and the cost is low.
4. It is not suitable for detecting an opaque and irregular crystal. The crystal of the cut surface is not applicable because it is considered to change the refraction and reflection.

f, two -color examination: Natural amethyst has two -color, and false crystals have no duality.

This Crystal Museum of the East China Sea San Shi Crystal Museum introduced this unscientific reasons:
1. No need, there are many natural amethyst cotton bodies, and more than 98%of cotton bodies are not natural. Setting and pendants are 1.99%of them.
2. Two -color is the term, it is difficult for everyone to understand.

g, check with a magnifying glass: Use a ten -fold magnifying glass to check under the transmission light, and the bubble can basically be fixed as a fake crystal.

It experts from the East China Sea Shengshi Crystal Museum introduced this unscientific reason for this article:
1. Some crystals are parcels, such as water gallbladder, which is easily mistaken for bubbles.
2. Generally, the glass has air bubbles, but there are occasional artificial crystals.
3. Ten times the mirror is too small.
4. The cotton body of the natural crystal inside will be mistaken for bubbles.
