Diamond rings are still the mark of splendor and wealth. Most women crave the perfect diamond ring and the larger and more expensive the better. When purchasing a diamond ring there are certain rules you really want to abide by to ensure that you are purchasing the best value for your money. Diamonds are measured in value by certain aspects such as the clarity and cut of the diamond, the clarity basically means how clear it is and the cut is how well the stone has originally been cut. If either the clarity or cut are poor the diamond rings will lose value.
