Emerald-cut diamonds are characterized by step cuts and a long table. Although emerald-cut diamonds are less brilliant than round diamonds or princess diamonds, they are revered for their clarity. Emerald-cut diamonds are known for their angled corners and step-cut, as well as their rectangular shapes. Because of their long table, inclusions are more easily seen on emerald shape diamonds than other more brilliant cuts. Emerald-cut diamonds are named as such because the cut was originally only used on emeralds.
Cushion diamonds are an interesting combination of rounded corners on a square or rectangular frame. There are two cutting styles for this shape: Cushion Brilliant, which is a more vintage cut with chunkier facets and larger flashes of light return, and Cushion Modified Brilliant, which is more akin to a modern-day round diamond cut with smaller facets and more rapid light return. Cushion cut diamonds have been around for over two centuries and as a result, offer a very antique feel for an engagement ring.
