Like near-colourless diamonds, brown diamonds can be cut into almost any shape.
Octagonal
Sometimes called emerald cut, this is usually base on an oblong, with cut corners, but can be based on a square instead, as shown. From a gemmological point of view, square is better than oblong, as it can be closer to the perfect proportions of a round stone, whereas oblong stones must necessarily be less than perfect proportion.
Round Brilliant
As with other diamonds, the modern round brilliant cut remains the most popular cut.
Heart Shape
The heart shape is a modification of the round brilliant cut. We think it suits brown diamonds better than it does near-colourless ones.
Pear Shape
The pear shape is similar to the heart shape in that it is also a modification of the round brilliant cut. We think it suits brown diamonds better than it does near-colourless ones.
Princess Cut
The princess cut is the most successful of the modern cuts developed for diamonds. It combines the square shape with the brilliance of a brilliant cut.
Marquise or Navette Cut
The marquise cut is also an adaptation of the round brilliant cut, which we believe also looks better in fancy coloured diamonds than it does in plain vanilla.
