Beauty of diamonds magnetizes people to have this amazing gemstone. There are hundreds of diamond jewelers both online and offline and you can purchase perfect one according to your penchants and budget. But you require proper knowledge about diamonds before you make a deal. These days, market is full of fake diamonds and there are great chances to lose your hard earned money for such phony diamonds.

So it is vital to put diamonds under following test before you buy diamond jewelry. With the help of fog test you can find out whether the diamond is real or fake. Hold the diamond and blow some air from your mouth on it. If the diamond is real then the fog will vanish instantly. But on a fake diamond, the fog will stay for few seconds.

With the help of ultra violet radiations you can easily test the purity of your diamond. A real diamond will release blue light when ultra violet light is passed through it. Diamond tester is another way to find the difference between a real and fake diamond. It is an electronic tester. Most of the fake diamonds are cubic zirconia. It looks like real diamond but weight of cubic zirconia is 50% more than real diamond of same size and weight.

Transparency test is also a good technique to check the quality of your diamond. Put the stone on newspaper and if you can see and read the newspaper properly then it is a fake diamond. Check the stone under 10 x magnifying glasses and avoid purchasing a diamond if you see several carbon deposits in the stone. Always buy diamonds certified from AGS or GIA. Sometimes the jewelers sell diamonds with a diamond grading report of their own private labs. Don’t buy such type of diamonds.
