Diamonds are expensive and often used in high-grade jewelry, such as diamond rings, necklaces and bracelets. Their handsome appearance is as good as their face value, which is the heart of many collectors. But as the saying goes, "Interlacing is like a mountain", the authenticity and quality of diamonds need professional instruments to identify, not just by eyes like antiques. Therefore, when buying large grams of diamonds, stores are often required to conduct professional testing.
There are many commonly used diamond tools, which can also be bought in professional goods stores. Compared with manual and other basic identification methods, professional instruments are more regular and convincing both professionally and technically. In fact, it is also very interesting to identify diamonds with professional tools. I believe many friends who have had experience in diamond appraisal have this feeling. Ok, let's get familiar with the tools for professional diamond identification.
Thermal conductivity meter: Thermal conductivity meter is a traditional method to identify the authenticity of diamonds. Of course, it has stood the test of history and is the most reliable diamond identification tool today. Thermal conductivity instrument uses the thermal conductivity of diamonds to transfer heat from one area to another through substances, and is engaged in the work of detecting the authenticity of diamonds. The thermal conductivity meter is very simple to use, just need to connect with the diamond. If the diamond is natural and real, the thermal conductivity meter will beep and light up a red light.
Hardness tester: As many friends know, diamond is the strongest crystal in nature, also known as "Jin Gangzuan", and it is the core component of many high-strength tools. In fact, the hardness of diamonds can also be used to identify the authenticity of diamonds, such as hardness tester. The hardness tester is very simple to use. Just compare the hardness of the diamond after the test, and the hardness greater than 9 is the real diamond.
Specific gravity liquid: Specific gravity liquid is a common tool and a new way to identify diamonds. As we all know, every substance has its own weight and density, so it is very reliable to test the authenticity of diamonds by specific gravity. The specific gravity of this diamond is 3.52. After the diamond is put into the specific gravity liquid, it sinks into the real diamond, otherwise it is a fake.
The above are the tools and operation methods needed for diamond identification. You can identify the authenticity of the diamonds you bought according to these.
