Hence it is best to go for a moderate cut. To choose a clear diamond: Since a trillion cut with the right depth offers such great brilliance and fire that it does an excellent job of hiding any blemishes or inclusions on the stone. Hence all you need to do it to go for a clarity grade that appears seamless to the naked eye. There is no reason for you to spend extra dollars over a higher or a flawless clarity grade. You just need to go for a diamond that is eye clean, i.e., it does not have any visible inclusions and blemishes. To choose a colorless diamond compared to its setting: Similar to the diamond’s clarity there is absolutely no need for you to select a diamond with a higher color grade such as a colorless grade of D, E, or F. In fact, it would be better to choose a diamond that would appear colorless to the naked eye in its setting.
