                                                                                        Report
                                                    
                                                        The setting, or the way jewelry holds a diamond in place, is an essential factor to consider when choosing an engagement ring. This feature can influence a ring's appearance, brilliance and longevity. Plus, many people prefer specific settings over others. Jewelers can set diamonds in engagement rings in various ways.

                                                        Our Four C's of Diamonds guide can help you decide on the most important factors when shopping for a diamond. The word carat derives from the word carob, a Mediterranean seed, which has an extremely consistent weight for measuring. The greater the carat weight, the rarer, and more valuable the diamond becomes.
