There are so many diamond simulants currently on the market and cubic zirconia stones are one of the most common of them all.  So how can someone tell a cubic zirconia from a diamond? Well it turns out it can be harder than you might think to tell the difference between them.

A diamond tester is one method, it is a machine that will tell you if the stone is a diamond, but it will not tell you what makes up the stone if it is not a diamond. Another method is using a jeweller’s loupe or a microscope. The jeweller or you can look through the top of the stone, focusing your vision toward the bottom facets of the stone.  If the lines appear doubled, like you have blurry vision, you ar looking into a sythetic stone.  If the lines are still singular, and very clear and distinct you have a real diamond.

You will also notice either through a loupe or micrscope the presence of inclusions or internal flaws. Because diamonds are naturally occuring stones they will have little inclusions within the stone, unless of course you have a flawless stone, these are rare and very expensive. Synthetic stones like cubic zirconia will have no flaws visible at all indicating it is not a diamond.  However, because some diamonds are flawless this method is not completely reliable but in most cases it will be a very good indication.

Home testing methods are great however use a jeweller you trust to take a look at your jewellery and give you peace of mind that what you have chersihed for so long is indeed the real thing.
