Round Cut Diamond Engagement Ring

As cutters became more knowledgeable over the centuries, they learned how to subtly change the angles of each facet and their facet shape. Even a slight modification can impart a huge impact on how the diamond sparkles. Today, round diamond engagement rings remain the most sought-after cut — and we know a lot of those fans adore just how much their round brilliant scintillates even way across the room.

And its small wonder that the round diamond engagement rings is the industry’s most popular diamond shape. This beautiful shape optimizes the stone’s scintillation in a spectacular way. A well-cut round diamond refracts light and reflects it back to the eye in a remarkable way unlike other cuts. The classic 57 or 58 facet round brilliant diamond represents the pinnacle of diamond cutting. And so many diamond settings are made for this iconic cut, that you never have to settle for a setting — there are going to be more choices than you could have ever anticipated. Lucky you if you’ve selected the round cut diamond.

If you adore a timeless round brilliant diamond shape, you’re in good company. This classic gemstone cut beats all the others for creating an over-the-top dazzling display of light to any stone, but especially with a diamond. This shape is called a round brilliant, and it lives up to its name. The masterful facet arrangements optimize light performance in the stone, returning all the light back to the viewer’s eye for a jaw dropping sparkle.

A round brilliant cut stone has 57 or 58 expertly polished facets all carefully positioned to reflect the most amount of light back to the eye. And isn’t this what we love about diamonds? Their exceptional scintillation draws us in and hypnotizes the serious diamond collector. Look for well cut round shaped stones, which optimize their light handling by delivering symmetrical light return.

The round brilliant diamond engagement ring shape fits perfectly in so many settings, especially a bridal set with a matching engagement ring and wedding band. The ageless appeal of round diamonds means that your own stone will look fresh and modern years from now. Whether large or modestly sized, a round diamond shaped stone is classic WOW!
