Ahh, just noticed the title gives a different name to your post - I found this in auction orders:
Gothic Angel Statue, Unique
That 'unique' status doesn't give much hope you'll find another.
Also, no sales on auction. It didn't drop in global so no way to tell what dropped it. The guy who looted it hasn't played for 2 years so it could be dumped in his storage never to be seen again (unless you know it's somewhere else).
