Xenia Alexandrovna received these boxes in London, and they were opened at Buckingham Palace in the presence of the King & Queen. She found nothing of value at FIRST, then later burned all of the clothing.
Sophie Buxhoeveden, wrote to Xenia to ask her if she retrieved the jewels that were in one of the boxes hidden in some clothes. Buxhoeveden gave her the exact location of the jewels in the box, Xenia went back to the box and found the jewels.
The type of jewels, their value, and shape are not listed, nor a provenance of any of the jewels, nor is there a list of what Xenia receieved in those boxes.
I am not sure what of their personal property made it back to England..
