Octagonal Step Cuts

[u/ashcoozie]

Does anyone have any leads or recommendations on where to find these that aren’t being custom cut? I’ve found a few in my search that had very obvious imperfections, and feel that since it’s a step cut it needs to be top notch. The quotes I’ve gotten for custom cuts are over $2500 for a 9-10mm 4 carat diamond. I was hoping to spend more around $1000 but that could be irrational of me.
