Learning How to Tell Cubic Zirconia from Diamond
Diamonds are relatively rare in the world. This rarity equates to higher prices and also to a limited number of stones on the market at any one time. Cubic zirconia has become the single most popular alternative to diamonds, due to the lower price of the stones and their amazing similarity to natural diamonds. However, learning how to tell cubic zirconia from diamond can put you in good stead if you're in the market for a real stone.
How do you tell if the stone you're looking at is cubic zirconia or a natural diamond? One of the first things you should look at is the facets of the stone in question. You will need a jeweler's loupe for this, or a microscope. On a true diamond, the facets will be very clean, with a knife-like edge. On a cubic zirconia, the edges of the facets will be more rounded. In addition, facets on a CZ are usually much more uniform than on a natural diamond, due to the need to conserve mass on a natural stone.
Another option in how to tell cubic zirconia from diamond is to weigh two stones of the same size and proportions. Cubic zirconia is 1.6 times heavier than diamond (greater density). Therefore, if your stone seems like a lightweight in comparison to a cubic zirconia, then you probably have a true diamond.
Yet another way in how to tell cubic zirconia from diamond is to check the flaws within the stone. Of course, you'll need a loupe or a microscope for this, as well. If you see tiny flaws and inclusions within the stone, it's pretty likely that you have a real diamond. CZs usually have no flaws at all (or very, very few). Of course, a jeweler can help you make the distinction in a short time, as well.
