Square-cut or Asscher-cut, diamonds are a popular diamond shape that are characterized by a step cut. This cut results in less light return when compared to their more brilliant alternatives, but offers a more vintage appeal. Square-cut diamonds feature cropped corners, which give it a unique, almost octagonal shape. Square-cut diamonds became very popular during the 1920s and as a result, are a desirable diamond cut for a vintage looking engagement ring.
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.
