I think those pinball crosses are close, but more like the one's the holy men are holding in that scene.
I'm pretty sure Vlad's didn't have a jewel in the middle. It may not even of had a Jesus carved into it.
But the one's in the pictures I found, are from the right historical time frame and area. So that's why
I referenced them.
I'd rather have it flat, no jesus, no jewel, but still with some of the design in that
main picture I sent you.
Based on the shape of the back of the cross, this(without the jesus)
would be more likely a realistic front. And all gold would look amazing.
