What setting is best for a diamonds?
'Best' is a judgement, and you are the judge.
Setting a diamond is motivated by the quality of the diamond. Your jeweler can best answer this question once you've chosen the diamond and decided how it will be worn.
'Best' is a judgment and you are the judge. Take your diamonds and their settings to a certified gemologist, who will help you document the diamonds as to their clarity, colour, cut and carat weight, and who will also help you determine composition of the setting metal.
