1. Where can I buy a loose diamond?
We usually choose to go to a jewelry store for safety.
Second, the method of identifying loose diamonds:
1, white paper identification method
This is the most practical method. First, find a piece of white paper and draw a horizontal line. Now put the front of the diamond down and cover the horizontal line. We look down from the back. The transparency of real loose diamonds is very high. If we can see the horizontal line clearly through the bare diamond, it means it is true. If the horizontal line is bent, it is counterfeit money.
2. Breathing method
Breathe on bare diamonds. If the water vapor on the surface of a loose diamond dissipates quickly, it is true. On the contrary, it is false, because the thermal conductivity of bare diamonds is very high, and only fake bare diamonds have high thermal conductivity. However, this method is more suitable for large loose diamonds, and small loose diamonds can't be seen clearly.
3, oily pen line drawing
Find an oily pen and draw a stroke on the bare diamond. Real diamonds with clear marks and fake diamonds with intermittent marks. Because naked diamonds are very lipophilic, and counterfeit products do not have oily characteristics. So this method can be used to identify the authenticity of a loose diamond, but you must first have an oily pen.
4. Drip method
Dropping water on the loose diamond surface means that water can expand and stay there for a long time, which is true. Because the loose diamond is hydrophobic, the water droplets will not disperse immediately. This method is more suitable for larger loose diamonds, because it is difficult for small loose diamonds to stay on them.
5, the fire observation method
Observe the angle change of the naked diamond fire color, and the naked diamond will have fire color under the light. Observing from multiple angles, if the fire color has a sense of jumping, then the bare diamond must be true. The real bare diamond has a kind of luster, which is very strange, with high refractive index and high dispersion value. There is no such "fire color" for fake naked diamonds.
Do you know where to buy loose diamonds? Generally, jewelry stores sell loose diamonds, which are cheaper than finished diamonds, but there are also some fake and inferior products and fakes in jewelry stores, so you must learn to distinguish between true and false when buying. We can use the above identification method to identify the authenticity of a loose diamond. In addition, you can bring some friends who have bought loose diamonds for reference. The prices of loose diamonds in different jewelry stores are different, so you can shop around.
