Fancy shaped diamonds refer to any diamond shape other than round. The prevalence and choice of a particular fancy cut is most of the time influenced by fashion and fame. For example, if hearts are popular, you will see a lot of heart shaped diamonds. There is a big diversity between the shapes; they vary between princess, radiant, emerald, asscher, cushion, oval, marquise, pear, heart, trillion and round, the traditional and most popular brilliant. The proportions of ‘fancies’ are unique and very precisely cut.
