A rose cut diamond has a flat bottom, with no pavilion, and a domed top containing only 24 facets. This lack of a pavilion means the cut also lacks the optical properties of a more complex cut which incorporates more than twice the facets and a deep pavilion.
Put simply, the rose cut is only the top section of a typical diamond, without the bottom part.
The most notable features of a rose cut diamond are their flat back and domed top covered in triangular facets. The number of these facets can vary from as few as 3 up to as many as 24, which terminate at the very top in a single apex. This is where the term “rose” from its name originates; It’s facets are said to resemble the petals unfolding in a rose bud.

With anywhere from three to 24 triangular facets, rose cut diamonds peak into a dome or kite-shape. This structure resembles the soft curve of a rose petal, hence its name.
