It is important to understand or have a basic knowledge on differentiating a fake and a real diamond. This would make sure that you are not committing any kind of financial mistake or investment. The best thing that you could do to check on the authenticity of your diamond jewelry is to take it to an independent and professional jeweller to get it appraised.
However, there are simple things that could do that would help you make smart decisions when choosing your diamond jewelry.
Making a good decision would rely on how educated you are. Learn about diamonds or the 4 Cs of diamonds: color, cut, carat and clarity. There are numerous websites that offer an insight on how you could determine the quality of a diamond based on the 4 Cs.
Working with reputable and trusted jewellers would also make sure that you are not getting involved in any kind of fraudulent transactions. It could be a those national and big chains or you could work with a local jeweller, whats important is that you are working that already has an established reputation in the business.
It always pay to ask the retailer. There are some jewellers who would not offer information unless you ask them. For example, you could ask the retailer if the diamond jewerly you are fancying is indeed jewelry or a similar stone called the moissanite. Ask questions about the stone or jewel.
Settings would give you an insight if you are getting a true diamond. Since diamonds are expensive stones, it is normal that it would be mounted on a setting that would compliment its value. If the setting is poorly crafted then it is likely that you are not getting a valuable stone.
Some would say that fake diamonds sparkle like rainbows. It is true. A real diamond would give off shades of gray when sparkling. Those that give rainbow shades are most likely copy cats.
Another test that most buyers would do would be transparency test. It could be done if you are buying loose diamond stones. This would allow you to put the stone on top of a newspaper and check if you could see through it. If you can then you could be dealing with a bogus stone, since diamonds would not properly disperse light.
Diamonds are known to be one of the hardest stones out there. So check if the diamond jewelry bears any kind of imperfection like scratches, nicks, etc. Diamond jewelries are still capable of sustaining such defects, but too much scratches or imperfections could be suspicious.
Diamond certificates are also another proof that the diamond jewels are for real. A jeweller or a retailer would offer this certificate along with the purchase. You could get a certificate from the GIA or EGL.
However, fake diamonds are not always bad. You could get them affordably and almost has the same look as the real diamonds in untrained eyes. Since it is more affordable, lost or damaged jewelries would be easier to replace. Aside from that any jewel, diamond or fake jewelry, cannot exceed the intention and sincerity of the person who will be giving it.
