I'm sorry I didn't see this sooner! I'm on the forums fairly regularly, but not all the time.
I'm not exactly sure what info you are after, but if it helps, I didn't import to Aus - as I'm currently in Europe it was cheaper and easier for me to fly to the US and collect.
A couple of months ago I was trying to decide between the AVR and the AVC, and since I live in Aus, I was hoping to see if we lived in the same city. I am in Melbourne. I was also wanting to see your gorgeous VC Sophie!
I will have the stone set in the US and I will be importing the ring to Aus. I recently got something from ERD, and the importing was not a problem. So I am not too worried about that.
