I was initially going to do this with the 6.5mm Asha ACC but I have decided to either use my 7mm Asha OMC or my 8mm Kashmir Diamond cut Sapphire.

Here are the CADs (keep in mind these were made for the ACC, but we are changing that).
So -- 8mm Kashmir Diamond Cut Sapphire OR 7mm Asha OMC (or keep the 6.5mm ACC)
