How to distinguish true from false crystals
Among the hot topics in the past 10 days, the identification method of crystal has become the focus of many consumers. With the popularity of crystal jewelry and ornaments in the market, fake and shoddy products have also increased. In order to help everyone better identify the authenticity of crystals, this article will provide structured data and practical methods from multiple perspectives.
1. Basic characteristics of crystal
Crystal is a natural mineral with unique physical and chemical properties. Understanding these characteristics is the basis for distinguishing true and false crystals.
| characteristic | real crystal | fake crystal |
|---|---|---|
| hardness | Mohs hardness 7 | Usually below 7 |
| luster | glass luster | plastic or resin gloss |
| temperature | cool to the touch | Soft to the touch |
2. Visual identification method
By observing the appearance of the crystal, you can initially determine its authenticity. Here are a few common visual identification methods:
| method | real crystal | fake crystal |
|---|---|---|
| inclusions | Natural inclusions or cracks | Bubbly or flawless |
| color | natural transition | Too bright or uniform |
| refractive index | High refractive index, light bends significantly | Low refractive index, direct light |
3. Physical testing methods
In addition to visual observation, some simple physical tests can also be used to identify the authenticity of crystals.
| Test method | real crystal | fake crystal |
|---|---|---|
| Hardness test | Not easily scratched | easily scratched |
| Temperature test | Stays cool for a long time | rapid heating |
| UV test | No fluorescence reaction | There may be a fluorescent reaction |
4. Professional identification tools
For high-value crystals, it is recommended to use professional tools for identification. Here are several commonly used tools and their functions:
| tool | use |
|---|---|
| magnifier | Observe inclusions and surface features |
| polarizer | Detect birefringence |
| density meter | Measure density and differentiate materials |
5. Purchase suggestions
In order to avoid buying fake crystals, consumers are advised to pay attention to the following points when purchasing:
1.Choose a reputable merchant: Give priority to merchants with qualifications and reputation, and avoid purchasing from unknown sources.
2.Request a certificate of identification: High-value crystals should be accompanied by an identification certificate from a professional organization.
3.Observation from multiple angles: Before purchasing, observe the appearance and luster of the crystal from different angles to ensure it matches the characteristics of natural crystal.
4.price alert: If the price is much lower than the market price, it is likely to be a fake.
6. Summary
Determining the authenticity of a crystal requires a combination of visual observation, physical testing and professional tools. By understanding the basic characteristics of crystals and mastering common identification methods, consumers can purchase real natural crystals with more confidence. Hopefully the information provided in this article will help you make an informed choice when purchasing crystals.
