De Beers advertising over the last century has established a "tradition" that a woman should receive a diamond ring as an engagement symbol. There is nothing like the power and authority (even imaginary) associated with what these rings represent that is appealing to most men. However, all rings are not created equal.

Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of fair cut quality are still quite attractive, but they may not be as brilliant as the top 3 grades. Fair cut diamonds are proportioned to yield more carat weight from the diamond rough. Such diamonds may be attractive to budget-conscious customers.
Color In the near colorless category H color grade is the second best. Most H color diamonds have a very light yellow or gray tint that may be more noticeable when the diamond is placed on a white surface. Diamonds with H color grade appear white and are great values because they are more plentiful and as a result less expensive.
Clarity Inclusions and external blemishes in diamonds of SI1 clarity may be easy to spot under 10X power magnification. Location of the inclusions greatly affect their visibility to the naked eye. SI1 diamonds of good color produce as good of a sparkle as the more expansive VS graded stones of lower color. Excellent bargains may be fond in this category.
