On a side note, about 10-15 years ago the Romanov jewels toured the country, and I went to see them. Wowie!!!!! They had some of the most amazing things: tiaras in flower shapes with bees that moved when the wearer walked, strings of marble sized pearls literally as tall as the wearer and many other lovely objects. This was just some of the stuff that wasn't broken down and sold. The pearls in particular are amazing. At the time, there weren't really any cultured pearls, and a diver might find one or two amazing pearls in a lifetime, so each of these strands was several lifetimes worth of work.
