The average engagement ring diamond size in the United States is considered to be 1 carat, as about 60% of Americans tend to propose to their partners with a 1-carat diamond ring. Yet actually, this is a debatable topic because there are many factors that will affect the stone’s as well as your overall diamond ring size. One of those things is the ring setting. A good and appropriate diamond ring setting can make your diamond look bigger than its actual carat weight. Some of the suitable examples include illusion setting, halo setting, three stone diamond ring setting, etc. However, you must try your diamond rings on before making a purchase because it is not necessary that a huge diamond will suit your fingers. Ideally, larger diamonds are perfect to make your fingers look elongated and slimmer. If you are tight on budget, you may go for some full-setting options as well. Another important feature that affects the diamond ring size is the metal band. Note that a simple and slim diamond ring band is ideal to accentuate the center diamond well.
