Round Cut Diamond FAQs

Whether you’re deciding on a cut or the best diamond setting for your center stone, our diamond specialists provide personalized guidance to help you make an informed choice. Reach out anytime, and let us help you create your dream diamond piece.


A round cut diamond is also referred to as a "round brilliant cut diamond" due to its facet arrangement, which maximizes sparkle and brilliance. Perfected over centuries, this time honored diamond shape is the go-to choice for crafting classic and stunning jewelry.

Yes, round cut diamonds are generally more expensive than other shapes due to higher cutting costs to achieve their iconic brilliance, significant material waste during cutting, and their superior light performance. Their popularity and high demand also drive up their price, as round diamonds are the most sought-after shape for engagement rings and fine jewelry.
Additionally, stricter grading standards for round cuts ensure a higher-quality product but further increase their value. Non-round shapes (like oval, pear, emerald, or marquise cuts) are often referred to as "fancy shapes" and can be up to 20-40% less expensive than round diamonds.

Thanks to their circular shape and optimized light return, round cut diamonds often appear larger than princess cuts of the same carat weight. This makes them a favorite for those seeking maximum visual impact and an eye-catching center stone.
This timeless cut is renowned for its ability to reflect more light compared to other shapes, giving it a breathtaking and captivating shimmer from every angle ideal perfect for diamond engagement rings or other jewelry.
