If you are in the market looking for a diamond alternative, you will find that there are dozens of gemstones marketed under a myriad of creative names. We know this can be very confusing, especially if you are just learning about diamonds and gemstones. We provide the following list of the more commonly marketed gemstones to assist you in your seach.
You will quickly notice that all of the gemstones can be grouped into 3 categories: 1) Diamond, 2) Moissanite and 3) Cubic Zirconia or CZ. Unfortunately many of the sellers of these CZ jewels are less than honest when it comes to their "scientific claims" and some will blatantly deny that it is a CZ at all. Why would they be embarrased to tell the truth about their gemstone? Please refer to the 'Moissanite vs CZ' section above to learn how the properties of CZ don't begin to measure up to Moissanite.
One seller of CZ jewelry, DiamondNexusLabs.com, has engaged in such an elaborate campaign of deception that we have provided a more detailed analysis of their CZ jewel as a public service. Click here to learn more.
