I hate to say this…but I must…Simpsonite is in my experience, well the only word that best describes it is, dull. From what I see in your photo those stones are NOT dull. Simpsonite does not have that type of clairity nor shine. Someone must have given you a wrong diagnosis. 
I know I will be slammed for my verbiage but it’s Friday. I had some nice “clear” Simpsonite in college but that was a lifetime ago and heaven only knows where they are now. Trust me they did not have near the shine that your stones have. I hope that you indeed do have Baddeleyite. If not and they are indeed Simpsonite they are quite unique specimens.
All the very best
