Because natural zircon is radioactive and harmful to humans, it must be treated before it can be worn. That is why the zircon sold on the market is basically man-made, also called synthetic cubic zirconia. Synthetic cubic zirconia is also graded. The appearance of zircon produced by legitimate manufacturers is even comparable to that of moissanite. It is not difficult for professionals to identify them. It takes a long time to wear a zircon before you can see the difference between a diamond. It also attracts a large number of consumers because it is much less expensive than diamonds, aesthetically satisfies people's needs, and allows them to spend less money on simulated jewelry.

How to identify synthetic cubic zirconia and diamond

 From synthetic gemstones wholesale We know that one of the biggest highlights of a diamond is its hardness. The Mohs hardness of a diamond is 10 and that of a zircon is between 6 and 7, so we can use the difference in their hardness to distinguish them. Look for stones with hardness in the middle. Draw a diamond and zircon table. If it is a diamond, then the table will not leave marks. If it is zircon, then sorry, the table is scratched. Don't think it's a shame to scratch off a zircon. Although zircon is a mid-range stone, you should not care when you buy fake diamonds (i.e. zircon) at a high price.

 Second, use a see-through effect to distinguish diamonds from zircons. Get a piece of paper with black lines and place the diamond and zircon table tops (note: tabletop, tabletop, tabletop) with the bottom line of the black lines facing up. If it is a diamond, you will not be able to see it. The black line on the paper is invisible because the cut of the diamond is usually standard and almost no light can pass through the pavilion facets (except in one case: unless the diamond is improperly cut and ground). This method actually uses the principle of the refractive index of the stone. The higher the refractive index, the less likely it is to be seen through. Thus, since zircon has a lower refractive index than a diamond, it is easier to see through than a diamond. However, the

 Lipophilic body. Wholesale gemstone suppliers have special tools. We know that diamonds are lipophilic, especially after touching them with our hands, it looks like it is covered with a film. So we can take advantage of this feature by drawing a stroke on a clean diamond table with an oil-based pen. If it is a diamond shape, there will be a continuous line. If it's a zircon, there will be interrupted dots. Of course, there is more to lipophilic bodies than that. You can also find a small drop of water on the table and see if the drop disperses. However, this test has limitations and is not recommended for personal use.

 IV. Weight. This method uses the relative density of the stone to distinguish diamonds from zircons. The relative density of diamonds is 3.52 and zircon is as high as 4.73, which means that the same volume of diamonds and zircon, plus the weight, the weight of zircon, the lighter is the diamond. I think this is sometimes inaccurate, rather than observing the instrument is more accurate.

 The above four methods are the easiest to distinguish between diamonds and zircon for consumers who don't know how to do it. Of course, those who know more can also make further judgments based on the basic properties of diamonds and zircons.
