Not all online diamond dealers sell you the highest-quality diamonds. Some of them even sell fake diamonds and it is important for you to stay away from them. In order to do that, you need to be able to tell the difference between real and fake diamonds, but most of the fake diamonds are unidentifiable from the real ones. Fortunately, there are some ways in which people can identify fake diamonds.
Here are some of the ways in which you can test if your diamond is real or fake.
Black Light Test
It is a very common test to identify fake diamonds. You will need a strong UV light to do this test. Examine the color of the stone under UV light to see whether it changes at all. It’s most likely an actual diamond if the stone has a bluish glow to it. This test, however, isn’t conclusive due to the way fluorescence in real diamonds works.
Blow hot air on the stone in a reasonably cool environment. You’re attempting to envelop the stone in warm, moist air. Your breath will not form a fog on the surface of a real diamond since it does not hold heat efficiently. However, a piece of moissanite, like your mirror or cell phone screen, will become fogged up quickly.
Examine your suspicious stone under a microscope first. Then compare the differences between the fake and the real diamond. Inclusions are internal or exterior imperfections that occur in real diamonds. If the other stone is cubic zirconia or moissanite, it will be free of internal and likely external defects. This is because natural diamonds are created in the earth, whereas cubic zirconia and moissanite are grown in laboratories.
The Candle Test
Heat the loose diamond with the tweezers for around 30 – 45 seconds over a candle flame. Drop it into frigid water as soon as possible. This dramatic temperature shift will not have any effect on a real loose diamond. During this test, however, many fake diamonds may crack or shatter, including ones composed of glass, cubic zirconia, or quartz.
The Newspaper Test
When you place a fake diamond on top of the newspaper, you won’t be able to make out the words on the page. A good-quality diamond will refract light so intensely that you won’t be able to see through it. Cubic zirconia, on the other hand, is more translucent, allowing you to look right through it.
If you want to buy real diamonds, make sure to choose reputed online diamond stores.
