A simulated diamond can be a girls best friend if she is looking for a bargain. The Clear Cubic Zirconia can have the same color aspects of a perfect colorless diamond. Hang on let me say that again, the $20 CZ can have the same color quality of a priceless diamond. The CZ often has more fire and is more brilliant then the real thing. This is one of the tell-tale signs of a man made diamond. The natural process by which real diamonds are made allows nature to insert its own imperfections, thus most natural diamonds have flaws, inclusions and are a little less fiery when compared to a CZ.
So if you are looking to save a little money and still look fabulous, then the CZ Diamond is the way to go.
