True crystal is a jewel, buying fake goods, and making money is not going to break the money!
Before distinguishing between true and false crystals, the word "crystal" is clearly defined. Whether it is in the formal jewelry sales industry or the authoritative jewelry identification industry, it refers to the same thing, that is, quartz crystal.
The "quartz crystal" is that many Chinese people will mistake shiny and transparent things, such as glass, as crystal, which gives the bad business a chance.
After the definition is clear, let's talk about identifying the true and false of the crystal.
Don't believe in false identification anymore! ! !
Seeing
[False identification] There are many ways to identify the true and false crystals on the Internet, such as natural visible uniform small horizontal stripes or willow-like substances, and fake residual water leaching residue, glass slag, and no natural impurities.
[Scientific Analysis] This is not reliable. The inclusions of gemstones cannot be called impurities, but should be inclusions, referred to as inclusions. As for the smelting materials such as crystal slag and glass slag, it is entirely taken for granted. The raw material of the glass is sand, and the synthetic crystal does not use dregs. On the contrary, the color is positive, the interior is clean, there are many natural crystals without ribbon, and there is no such thing as false.
Tongue
[false identification] Summer tongue crystal surface, there is a cool feeling, fake no.
[Scientific Analysis] If you use alcohol on fake crystals, you will also be cool, and many people will not dare to swear when they buy them.
illumination
[False identification] No matter which angle you look at, natural crystals can give off beautiful brilliance; fake ones will not work.
[Scientific Analysis] What is beautiful glory? The faceted glass is also 720° without glare. And more shiny.
hardness
[false identification] natural crystal hardness is large, take a light stone to gently stroke, no trace; fake streak.
[Scientific Analysis] This destructive experiment, who is who is stupid.
Hair silk
[Fake identification] Put the crystal on a hair, and the double crystal is natural crystal, no fake.
[Scientific analysis] Hair silk less than 5 cm in diameter, can't see that there is a double shadow in the wood? Because the crystal's double-fold rate is only 0.009, the light passing through it is less than a certain length, which is difficult to observe.
Thermal conductivity meter
[False identification] Adjust the thermal conductivity meter to the green 4 grid test crystal, the natural energy can rise to the yellow 2 grid, and the fake will not.
[Scientific Analysis] The thermal conductivity meter is also called the drill pen. It is used to measure diamonds. Which mechanism will take it to measure crystal?
Xiaobai is so authenticated! ! !
Crystal glass is more fake, and polarized lenses can distinguish between the two. Under the polarizer, turning 360°, there are four bright and four dark crystals, and no glass.
Prepare a dichroic mirror. Natural amethyst has dichroism, but no fake.
Checking the crystal with a ten-fold magnifying glass, the bubble can be found to be basically fake.
These are all required to use professional tools. How to identify without tools?
Very flawless and inexpensive crystal, it is recommended not to buy, because it is basically synthetic.
Buying crystals is too popular for ice, transparent, easy to use, such as "ice type yellow tiger eyes", obviously optimized, the seller does not say, give you a sky-high price, your mind is hot, bought it will be pitted .
Specific crystal, specific identification! ! !
The first category: If you buy crystals with obvious inclusions, such as green ghost, titanium crystal, hair crystal, red rabbit hair, etc., you can basically buy with confidence.
The empty tube inside the synthetic crystal will be dyed and impersonated, but in the end it is not a natural object, and its pipe is irregular. Unlike the natural hair crystal, the hair cross section inside has a geometric shape such as a square or a triangle.
Because of the high difficulty of fraud, there is little fraud.
The second category: If you want to buy white crystal, amethyst, citrine, green crystal, etc., you need to pay attention to the following points:
The color is highly uniform, and you should be vigilant; the natural colors can be approximated, but most of them will not be absolutely the same.
The interior is too clean, and no matter how careful you look, you can't find anything awkward. Be alert.
A string of these materials, see where the holes are punched. If the hole is sharply angled to the sphere, at least it can be proved to be crystal; while the glass replica will melt slightly due to the temperature generated by the hole, and there will be a circular arc or slight inversion around the hole (but some merchants will be in the beads). The hole is punched in the defect, so if you want to identify it accurately, you have to look at the certificate or review.)
In short, it is "one point for one price", don't be greedy and cheap, find a reliable seller, ask the other party for an authoritative certificate when purchasing, and if necessary, re-examine immediately, can effectively avoid fake crystal.
