I feel a growing acceptance of a new force in the round world. It the tourmaline rough meets the following criteria, it may end up being cut with a split horizontal main pavilion and a modified step cut crown.
1, The piece of rough has a deep enough profile to efficiently cut a deep round.
2, The piece of rough has a light enough tone level to benefit from a deeper stone.
3, The rough is of high enough quality to justify the added work.
This gemstone met the criteria and now sports an enhanced tone value in the yellow green color area. It appears to be eye clean and certainly is bright. It weighs 1.03 carats.
