In this video, I'm faceting a blueish green Montana sapphire into a standard step cut with parallel bars on the pavilion in multiple tiers.

My personal version of this design reduces the blackout amount and gives the finished gemstone a bright, full-color direction. It also offers a high yield for long, blocky rough that might lose a significant amount of mass in a deep brilliant design.
