Round Brilliant Diamonds

Jump to Hand-Picked Round Brilliant Diamonds

In contemporary times, the round brilliant diamond has become the most popular diamond shape for the engagement ring.

But diamond cutters have been studying and refining the round cut for much longer than the current popularity — and diamond cutters now use advanced theories of light behavior and precise mathematical calculations to optimize the fire of a round diamond.

Because of the popularity of round diamonds, all diamond stores are well-stocked with round diamonds, providing customers with the greatest range of flexibility in terms of balancing cost versus quality. In other words, whether you are on a limited budget or the “sky’s the limit”, you will likely be able to find a suitable Round Brilliant Diamond in your price range at most stores.

Choosing a Round Brilliant Diamond

For the round brilliant diamond, selecting the highest quality cut you can comfortably afford is important. For those that can afford it, “Ideal” or “Signature Ideal” is the perfect choice, but gorgeous diamonds can still be purchased with less demanding cut grades.

Our minimum recommendations for buying round brilliant cut diamonds are as follows (please remember these recommendations are opinion only, and your tastes may vary):

• Cut: Good
• Color: H
• Clarity: SI1
• Depth Percentage: 57-65%
• Table: 51-64%
