Synthetics such as cubic zirconia are so popular because for the untrained eye, they are like diamonds on discount. They look incredible but they do not cost that much. This is the reason that makes a lot of people go crazy for the look of diamond. For the aesthetic appeal, sure, the cubic zirconia fashion jewelry is a fun, cost effective option but then again, one should not dare to give someone an engagement or wedding ring because women will definitely know if you used the real deal or a synthetic stone. It looks good for casual use but for elegant events, nothing beats the real deal.
