Fancy colored diamonds, on the other hand, are extremely rare and very expensive. Eventually, these rings evolved into rings made of gold and decorated with engravings or other decorations. In 860 Pope Nicolas I made it a requirement to give a ring after a proposal to signify the engagement.

Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Ideal cut refers to the angles and proportions of a diamond that satisfy very precise mathematical formulas. The result is that the the ideal cut diamond internally reflects most light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing ideal-cut diamonds higher on the quality pyramid than deep or shallow-cut diamonds.
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 VS2 Clarity diamonds are very slightly included grade two. VS2 diamonds have minor inclusions that are visible at 10x magnification. They are less expensive than the VS1 clarity grade because they exhibit slightly more inclusions. VS2 clarity diamonds make excellent choices for jewelry because the naked eye will not be able to detect any inclusions.
