What a knack you have for finding interesting photos!

I know very little about the Russian royal jewels,so I am hoping some others might be able to throw some light on the issue.

The tiara obviously survived the revolution as seen in the photo released by the Soviets in the early 1920s.



In 1930 the tiara was said to be part of the Diamond Fund held by the Soviets.



But, as we all know some of those items were later sold -- for example the elaborate snuff box is now in the British royal collection.

Nevertheless, I strongly suspect that the third photo in Janet's post is a photoshop item showing the possibilities. When I looked at the pearls surmounting the tiara, I noticed that part of the central pearl is obscured. That can also be seen in the smaller version which has pearl surmounts.
