The portuguese cut refers to a particular type of faceting where the gem is cut with three rows (simple cut = two rows) of rhomboidal and two rows of triangular facets above the girdle (crown) and four rows of rhomboidal and one row of triangular facets below the girdle (pavilion). The portuguese cut thus has an extra row of facets on the crown, and this style enhances the brilliance of the gem. The portuguese cut is one of the most popular fancy cuts in the market and you'll find many varieties of gems cut in this style.
