It is usual to confuse the shape with the cut of a diamond, as they can be synonyms. So, what is the difference between shape and cut? Shape refers to a diamond’s form, the outline of the diamond (e.g. round, emerald, cushion) whereas cut describes how well cut a diamond is (e.g. excellent, very good, good).

When choosing a diamond shape, it is good to take into account your partner’s personal style, hand shape and size.
