I seem to recollect an image of Queen Victoria wearing the Oriental circle tiara and pearls was posted on this board, but I have not found it yet.
Edit: I finally found a copy of the image on the Royal Order of Sartorial Splendor site, but I am sure it was posted on this site at some time. Please scroll down to see the image of Queen Victoria wearing the Oriental circlet tiara and two strands of pearls. http://orderofsplendor.blogspot.com.au/2012/03/tiara-thursday-oriental-circlet.html
