Because of modern technology, it is becoming very easy to replicate a diamond and sell it as the real thing. There are a few things that you can do to help you spot a fake diamond.
• Only deal with jewelers that have a good reputation
Always do your research before making a large investment, reguardless of what it is you are buying
• Ask to see the diamond certificate
If there is no certificate, the diamond is not real. RUN!
• Check out the piece that the diamond is sitting in. It is more likely that jewelers will not put real diamonds in low quality metals
• Look for scratches or nicks- Diamonds are very durable and will not usually get scratched or nicked (especially if its supposed to be brand new)
• If you decide to purchase the diamond, make sure that there is a return policy. Immediately upon purchasing, take it to other stores and get it appraised. If there is any doubt by the person who does the appraising, return it and report them!
It is almost impossible to completely avoid being scammed. The majority of the people in the world are very honest, but do not think that everyone is on honest. Use your best judgment in any situation!
