Read on for a guide to round-cut engagement rings, plus editor-approved picks you can shop right now.
What Is a Round-Cut Engagement Ring?
Round-cut diamonds have a uniform and symmetrical shape made up of 58 facets, which qualifies them as a brilliant cut. The traditional round brilliant cut stones were deliberately designed with 58 facets to give them their distinct sparkle. Simply put, no other diamond cut can compare with the brilliance of a round-cut diamond.
Round-cut diamonds account for about two-thirds of all diamonds sold, making them the most popular diamond shape on the market. While they are the most popular and widely available option on the market, they are also the most expensive. Why the hefty price tag? Demand and what is called rough wastage. Up to 38% of a stone is wasted when a diamond is cut into a round shape, making it the most expensive diamond shape to create.
What to Look For in a Round-Cut Engagement Ring
Before purchasing a round-cut diamond, pay attention to the the 4Cs (cut, , clarity and carat). The cut grade of a round diamond is very important, as it determines the stone's brilliance. You want a proportionally cut diamond that isn't too shallow or too deep. However, a round-cut diamond can easily conceal mild color variations or inclusions (read: internal flaws) because of its brilliance. So if you aren't obsessed with buying a colorless, flawless stone, you could get away with a really well-cut round diamond with slightly lower color and clarity grades—and save yourself some money in the process. Pro tip: If you're buying a loose stone, you can ask a GIA-certified expert to evaluate it before you have it set.
Why Choose a Round-Cut Engagement Ring?
For over 100 years, diamond cutters have been perfecting the process for cutting round diamonds. Thanks to their 58 facets, the brilliance of a round-cut diamond is unparalleled. So, if you're in the market for a center stone with megawatt shine, this is the diamond cut for you.
Another huge pro of round-cut diamonds is their versatility. They look chic in solitaire settings, in modern bezel settings or framed by glamorous diamond halos. They also posses a timeless appeal that pairs well with any type of precious metal.
