earth angel jewelry wholesale How to distinguish between the true and false diamond materials of the diamond ring?

afro jewelry wholesale Diamonds are very precious high -end decorative supplies and are also necessary jewelry for marriage. However, diamonds are not only expensive but also rare, so many fake diamonds also appear on the market. So everyone must know how to distinguish the authenticity of the diamond ring.
On how to distinguish the authenticity of diamond ring:
1. Hardness test
The diamonds on the diamond ring are the hardest materials known as humans. There is nothing to draw on the diamond. The traces are not diamonds.
2. Catering oil test
The diamonds have strong liquidity. When we touch the surface of the diamond with our hands, we will feel sticky, that is the real diamond, because the person will secrete thin oil and strokes the hand, touch the touch, touch the touch, touch the touch, touch the touch, touch the touch, and touch it. Diamonds are adsorbed, making us feel sticky.

3. qi test
The breath on the diamond ring. If the water vapor disappears immediately, it is the real diamond, and otherwise it is imitation.
. Perspective test
Man the diamond table down on a piece of paper with lines. If it is a real diamond Light, so diamonds can't see the lines on the paper.

5. Cleence test
diamond is a pure natural product. In the process of forming, there will be impurities. We can carefully observe the inside of the diamond in 10 times. Most of them may be fake diamonds.
6. Observe the reflection light
The can observe a very thin matte and glitter reflex light with a magnifying glass to observe the waist circumference of the diamond. The characteristics of diamonds are unique.

7. Thermal conductivity test
The diamonds on the arm or face. If it feels warm, it is a fake diamond. Because real diamonds do not pass heat, no matter how you touch it, it is cool.
8. Certificate verification
It now buy a diamond ring with a diamond certificate, check the comparison carefully, and see if the diamond certificate records the diamond information on the diamond. The certificate will not be fake.

How to distinguish the authenticity of the diamond ring -common fake diamond material
1. Crystal and yellow jade
These two natural mineral transparent crystals are a bit like diamonds after thinking about , But lack of flashing colored light. And they are "non -average body", and diamonds are "average body", which is easy to distinguish with polarizers.

2. Glass
The fake diamonds made of glass is easy to distinguish, because its discount rate is low, and there is no flashing color light of real diamonds. Know. In addition, a bowl of clear water can be used to use a white porcelain bowl. The colorless glass products that are impersonated by diamonds can not see its contour in the water, and the outline of the real diamond is very clear in the water.

3. The vermiculite
It before the emergence of artificial cubic oxidation, the vermiculite is the best diamond substitute. The vermiculite has a strong double refraction, that is, it has two discounts, and the difference between the two discounts is large. As a result, a very special optical phenomenon is generated. When observing the observed vermiculite edges and gems with a magnifying glass, it can be seen from its top surface that the bottom surface and ridgeline at the bottom are obvious. Because diamonds are "homogeneous body", there is no phenomenon.

. Cube oxidation (that is, "Soviet Diamond")
This is the most ideal diamond substitute or impersonal product launched by the original Soviet Union. It is an artificial compound and no natural mineral. This is because cubic oxidation is close to natural diamonds in terms of discounts and scattered. However, its hardness (8.5) is 1.6-1.7 times that of diamonds, up to 5.6-6, and the heat conduction is much lower than that of diamonds. Therefore, it can still be used to distinguish it with diamonds accurately.

5. Artificial spinel
The difference between it and diamond is that the lack of flashing color light, immerse it in the two iodine methane, will also blur the outline, while the outline of the real diamond is the outline of the real diamond. Very clear.

6. Artificial gold red stone
Golden stone is an ordinary natural mineral. Its composition is titanium dioxide. Because of its discount (2.61-2.90) higher than diamonds (2.42), it is even higher. Therefore, the bright and dazzling flash can appear after thinking about the gem, and the rainbow -like change can appear, which looks very beautiful. However, because the golden redstone has a strong discount rate, like the vermiculite, the significant double shadow of the bottom edge can be seen from the top surface with the magnifying glass, so it is easy to distinguish between the diamond.

7. Artificial sapphire
The colorless and transparent artificial sapphire can also be used as a substitute for diamonds after pondering. But it almost disappeared in the "iodine methane", and the edge of the real diamond was dark and very clear.
