The expansion data
1. The gravity test method: There is a proportion of the proportion of gemstones on the market; we can use a 3.32 specific solution to test the true and false diamonds. The proportion of natural diamonds is 3.52, and all natural diamonds will sink in the gravity water, so all gems floating on the proper liquid can be certain that it is not a diamond.
2, penetrating observation method: Diamonds have a high discount rate, and the higher the discount rate, the stronger the light reflection force, and the relatively low perspective. You can prepare a piece of paper with a straight line, and the two unknown diamonds to be determined are facing down, covering the straight line. Straight lines are definitely not natural diamonds.
3, the parenting method: Diamonds have a "oil absorption" for oil, and imitation diamonds have no such characteristics. Put the diamonds on the face with a small amount of oil and rub the diamond with your thumb. The thumb will feel a kind of sticky, not easy to slide, and imitation diamonds will make the thumb feel smooth.
4, qi test: natural diamonds have good heat transfer capacity, and the heat is scattered fast. The diamonds that are about to be tested are close to the mouth, gently breathe, so that the tested diamonds are covered with a layer of light mist. At this time, the diamond fog volatilizes immediately. If it is a natural diamond, the fog will immediately dispersing. It will be dispersed for a while to imitate the diamond.
5, measuring and weight: 1 carat's natural diamond, the diameter size is about 6.50 mm (0.65 cm). Most of the counterfeit diamonds are at the same weight of the same 1 carat. The diameter size and natural diamonds are always quite large. gap.
6, artificial oxidation 锆 imitation: higher hardness, good refraction, but reflection will reflect more color light when rotating, compared with the faint yellow and blue color light when the real product is rotated, there is obviously obvious ones. difference.
7, hardness test: Diamonds are the hardest natural generated substances. There is nothing to draw on the diamond. If you can draw traces, it is not a diamond.
8. Observation reflex light: Use a magnifying glass to observe a very thin matte -like and glitter reflex light at the waist circumference of the diamond. The characteristics of diamonds are unique.

The expansion information:
Since the diamond's crystal cells are five atomic tetrams, their crystal structure can be regarded as a tetraon combination connected to the top of the corner, and the rules are repeated and three -dimensional arrangement. Diamonds composed of tetraonal bodies are common in cube, octagonal, and diamond -shaped duodenal crystals. The surface is smooth and flat, forming a mirror -shaped, and there will be no smooth pattern or grooves. Those with smooth texture or grooves are imitation.
The real diamond hardness is extremely high. You can observe the waist of the diamond. If it is a sand -like waist, it is most suitable for this method. Because the diamond is harder than any imitation product, it will not appear thin stripes like a counterfeit.

wholesale designer style jewelry Basically, the certificates are credible. Of course, as long as the certificate is true. Everything in our country can be faked. Including certificates, including diamonds.
The diamond can be faked with ink mulberry stone. Hardness 9.5 is second only to diamonds, like heat guidance and diamonds. Only the refractive index of optics is different, the price is 1/10.
gia's laser engraving is also 20 yuan. The certificate can be found for a few dollars for the same size score.
Buk of our country without diamonds, to be imported, and international imports need to take the process of Jinbaili. The qualifications for getting started are very good, so 90%of domestic drills are smuggling. It is the big brand that is also "black and white". Do you dare to buy it?
As long as people can make it, China must be imitated. Do you dare to buy it? Fortunately, domestic businessmen are more serious businessmen, and generally do not deceive people to sell fake drills. However, the outrageous price is not allowed. (Of course refers to international offer)
, the certificate of GIA IGI in China is currently recognized in China. Because the network can be checked, there is a lettering on the drill. There is no problem with network check, but can you guarantee that the certificate is true? If you use a slightly worse drill and a fake certificate to give you. It is not that international certificates are 40%more expensive than domestic. GIA's appraisal fee is $ 80, and the lettering is $ 20. Internationally unified.
But now I think that diamonds in the domestic HRD certificate can not be fake, because the market share is low, what to do if fakes cannot be sold.
The possibility of big drill is very low. Because the certificate of the big diamond is given a flawed map, the flaws of each diamond must be different, and you know it at a glance at a glance. If imitation drills are generally average, the possibility of defects is small. And even if it is intentional to make flaws, it will definitely be verified in the appraisal agency.
