Michael of Greece said in a documentary that nuns visiting the Tsar & his family removed jewels & other valuables and his them in the area around Jekaterinburg. Though I'm not sure where he would have that information from.
There were several caches with valuebles,yes.Some are yet to be found,some caches ended up with the Bolsjewiks after a nun told them of its whereabout under treat of torture.
The IF was able & allowed by Kerenski to take many belongings with them to Tobolsk,a train load full..Among them many stones,pearls and jewellery,Much of that ended up in the clothes of the GD's,hence the murderers at Jekaterinenburg had a hard time to shoot the poor girls,the bullets ricochede all the time because of the GD's corsets filled with stones.Every time you see mentioned one of the GD's or the Tsarina say: "We attended to our medicine" she actually means jewellery.
Not all stones were as valueble,some were chrystals...as the murderers found out...and some of the belongings found at their graves in and near the Pig Ravine are on show in a small geological museum near the cathedral build on,or almost on,the spot where the Ipatiev house once stood.
I say almost on because,the Russian Orthodox Church didn't & doesn't see it beneath itself to mislead all as they have the exact spot where the cellar room was right outside the cathedral wall.They build an opulent Imperial Room in a sort of crypt as the exact spot where the Passion Bearers were killed.Wrong.The exact place of that room is exactly just outside the church,compare the floorplan of the Ipatiev House and that of the church and you'll see.Why on earth??The ways of the ROC are incomprehensible or it should be for their own political and ROC agenda only.I criticize the church for ongoing misleading and ask why?
But when at St.Petersburg last week,seeing the Icons of Nicolai II with Alexey,and the beautifull and huge icon of the Imperial Passion Bearers at the Cathedral of Kazan I was very pleased they're recognised and that so many people burned candles and layd flowers.Russia is coming to terms with it's Imperial past,slowly by slowly,bit by bit the awareness grows.
