Pear-Shaped Diamonds are typically a combination of a round and a marquise shape. A quality Pear diamond ought to have very good or excellent symmetry, and the point of the diamond should be in line with the apex of the rounded end. A pear-shaped diamond should be set with a prong at the point of the stone – this ensures that most flaws and inclusions will be covered by a prong. Pear diamonds typically contain 58 facets, which allows light to pass through the diamond much in the way light passes through a round diamond.
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.
