Note that you must be really careful while choosing such huge diamonds since millions of dollars are at stake here. In order to give you a clear idea regarding the same, below are some of the common mistakes that most diamond ring buyers make while choosing luxurious diamond rings.   The most important feature of a diamond is its cut.
