                                                  Setting Recommendations for D-Z Diamond Colors

                                                  Color is one of the most important factors in a diamond's overall beauty and value. When selecting a setting it's important to remember that the type of metal used can have a significant impact on how a diamond's color appears. White, yellow and rose gold settings can all affect how a diamond looks.
