Beaded WW1 necklace & belt

This red and metallic gray belt and necklace was handed down to me from my Grandmother..  It looks to be glass beads threaded together in designs that include the swatstika.  The envelope they were contained in for so many years reads the following:

Made by Russian Prisoners or patients, in 1st World War at hospital in Dijon, (I think) France. Given to me by Mme. Jane Clauzel who at that time, was a nurse in Hospital.  This was given to her by patient, as a token of affection and appreciation and she treasured it deeply but wanted me to have it.  S.L.H.
