|3 carat diamonds are a stunning choice for a loose diamond purchase or for an engagement ring. Ritani has a large selection of diamonds in the 3 carat range in a variety of shapes. Round cut diamonds are the most popular diamond shape, followed by the princess cut and the cushion cut. If you are looking for a 3 carat diamond that appears even larger, choose a marquise cut, pear cut, or oval cut diamond. These trending diamond shapes appear bigger than they really are because of their large surface area. Add extra sparkle to your engagement ring with a halo setting, or let your 3 carat diamond be the star of the show with a simple but elegant solitaire setting. All Ritani natural diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world. Remember, carat weight isn’t everything. Make sure to prioritize the cut grade of your 3 carat diamond - cut is the most important of the 4 Cs. Choose a premium cut grade, like Ideal or Very Good to ensure a sparkling, beautiful diamond.
