How do I spot a fake diamond?

For years, illegal operators have tried to pass off low-grade gems as valuable diamonds, all around the world (even in Australia, where counterfeiters have been known to import fakes from Asia).   These “knock-offs” are usually worth close to nothing, often not even one-tenth in value of the diamonds they resemble. 

While you may think that you are fool-proof to ever be conned, think again: thanks to the new diamond replicas on the market today, even jewelers have difficulty spotting a fake.  Here are some tips on for how to find the real deal.

Tips

• When looking to buy a ring, a reputable jeweller will tell you if the stone is a genuine diamond, a cubic zirconia or some other substance.  So just be sure to ask!  If you’ve already bought a ring elsewhere, but still aren’t sure, take it to a trusted jeweller who has the right instruments to verify its authenticity
• Always check the mount and setting on the ring as well – if a cheap stone has been used, chances are a cheap metal will also be used
• Diamonds are forever for a reason – they are superior at remaining scratch-free.  So if your stone shows signs of wear and tear (such as nicks or scrapes) then chances are, it’s a dud
• Still aren’t sure?  Get the stone appraised – independent appraisers affiliated with a professional organization, such as the Australian Jewellers Association, can produce a certificate detailing the stone’s value

Keep in mind…

If a cubic zirconia is surrounded by a high-quality diamond mount, then only an expert will be able to spot the fake

Moissanite, a new synthetic substance that only came on the market less than a decade ago, is now considered to produce some of the best imitation diamonds around.  Only a professional with the right equipment will be able to tell them apart. 

If buying diamonds over the internet, make sure you receive a grading report, and get everything in writing.  Do your homework – research the company, see if it is listed with any professional associations and then make your decision.
