$CZ Ring - Can It Pass a Diamond Tester? To find out more about cubic zirconia rings and real diamonds, go to: https://beyond4cs.com/faq/cubic-zirconia-vs-diamond/ In the jewelry market, you can find cubic zirconia rings everywhere from departmental stores to higher end chains. And they are really popular for good reasons. CZ is cheap, relatively durable and looks alot like real diamonds. Most of the cubic zirconia you find in jewelry are mass produced in China where production costs are low and the cost per carat being as low as a few cents. This inexpensive option coupled with its appearance make CZ suitable for both higher end and lower end jewelry. In this video, we are using a diamond tester on a $10 cubic zirconia engagement ring that I bought online. As you can see in the video, the gemstone tester accurately checks the ring out as a non-diamond ring. This quick examination only takes a fraction of a minute and gives you a very convenient way to perform identification tests at home. While this CZ ring can be identified easily with a diamond tester, I do want to point out that there are limitations to it. Some gemstones which have similar thermal conductivity like moissanite would not be accurately identified with a heat probe testing equipment. If you are a hobbyist or someone who wants a cheap and simple way of identifying CZ and other common simulants, you can buy this diamond tester here: https://beyond4cs.com/go/amazon-diamond-tester/ https://beyond4cs.com/go/ebay-diamond-tester/ For people who are more serious or require a higher level of test accuracy, I recommend the Presidium gemstone tester which can identify a wider range of simulants like moissanite. https://beyond4cs.com/go/amazon-presidium/ For more readings about CZ or spotting a fake diamond, check out these links: https://beyond4cs.com/faq/how-to-spot-a-fake-diamond/ https://beyond4cs.com/clarity/how-to-use-a-10x-jewelry-loupe/ https://beyond4cs.com/jewelry-guide/white-sapphire-vs-diamond/ If you want to buy a high quality diamond engagement and not get ripped off, these are 3 places that I highly recommend to check out first: https://beyond4cs.com/reviews/blue-nile/ https://beyond4cs.com/reviews/whiteflash/ https://beyond4cs.com/reviews/james-allen/$

$White Sapphire vs CZ vs Diamond - Can a Gem Tester Tell Them Apart? For a more detailed read on white sapphire, cz and diamond, go to: https://beyond4cs.com/jewelry-guide/white-sapphire-vs-diamond/ https://beyond4cs.com/faq/how-to-spot-a-fake-diamond/identify-a-moissanite/ White sapphire and cubic zirconia are both common types of diamond simulants found in the jewelry market place. They are used as an alternative to diamonds because of their cheaper prices and ability to be manufactured at scale. With white sapphire, a lab made gemstone will cost around $2 for a carat while a CZ will cost less than $1 for a carat. White sapphires also have a distinct appearance that is slightly milky while CZ will look identical to a diamond to the untrained eye. In terms of sparkle and brilliance, CZ is a better simulant because of its refractive properties and material quality. In terms of getting the best sparkle and scintillation, diamonds are usually in the top tier level. This is because their hardness allows them to be polished with extreme luster and better proportions that are planned beforehand. In this video, we performed a comparison of all 3 types of gemstones and used a diamond tester to check them for their authenticity. A real diamond will cause the diamond tester to sound out in a beeping fashion while a fake diamond simulant will not activate the tester. It is also important to note that while a cheap and affordable testing equipment like this can allow a lay person to identify a diamond, it isnt 100% fail proof. Some gemstones like moissanite will show up as a false positive and you need to perform further tests to confirm the unknown gemstones identity.
