Hi JJ,
I bought one last year. One of my favourites and you won't see many around the place. I bought mine at list which was Aus$8300.
If you go for it, enjoy wearing it.
When diamonds are graded you are comparing diamonds. If you want to compare diamonds with fake diamonds then you would be talking about zirconias or something similar and there is no comparison to a diamond.
It is the same with watches, IMO you can't grade a fake watch. They are all illegal and sent to try us.
Just my opinion and first post.
