Round Engagement Rings
The round diamond is the most popular diamond shape for engagement rings, and for good reason. Its 58 facets offer unparalleled brilliance and beauty. The versatile round shape makes it a stunning, classic choice in a wide range of engagement ring styles—from solitaire to vintage designs.
The brilliance of a round cut stone is its most appealing quality. You’ll want to look for an ideal or excellent cut diamond to ensure the most brilliance and beauty.
For Color in Round Cuts, we recommend a G-I grade, but specifically one that appears white in relation to its setting. For Clarity, look for an eye clean stone. In most round diamonds, you can find a VS1 or VS2 diamond that’s eye clean without paying more for a higher clarity grade. For the most aesthetic Round Cut, choose a length to width ratio of 1.00-1.03.
When designing your round cut engagement ring, consider the style you want long-term. If you want a classic look, consider a cathedral or solitaire setting. If you want a modern style, consider a channel set.
