Round Cut Engagement Rings

Shape

Round cut diamonds (also called brilliant-cut diamonds) are revered for their classic shape and incredible sparkle. Cut with 58 facets — or 57, if there is no culet — the round shape was designed to produce as much sparkle as possible. As sparkle is what many people are looking for when they buy a diamond, round cuts are immensely popular.

60% of the diamonds in our inventory are round-shaped, making it easy for you to find the right one for your needs. Not only are round cut diamonds the most sparkly, but they are also the most popular diamond shape. However, because they are the most sparkly and the most popular, this makes them the most expensive diamond shape.

Round cut diamonds are perfect for custom jewelry, such as earrings and pendants. To make your round cut diamond appear even larger, choose a halo setting. Or let your round cut diamond stand out on its own in a solitaire setting.

Lab Grown and Natural Diamonds

To complete your engagement ring, choose from our large selection of certified natural and lab grown diamonds. Whether you are looking for a 1 carat diamond or a 5 carat diamond, you are sure to find something that matches your expectations. Save 40% or more by choosing from our lab grown diamond collections.

All Ritani diamonds are certified by independent diamond grading laboratories. Our earth grown diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world, while most of our lab grown diamonds are certified by IGI, the most respected independent lab diamond grading labaratory.
