Hi Ariel,
It is a very nice old Choora that you have! I haven’t seen anything like this before - I mean a silver panel with turquoises on this kind of dagger… I have a Choora with similar handle and blade, but without this decoration. I do not think that it is a Bukhara dagger anyway
Mine has an old worn Arabian tag on the scabbard, maybe it can clear something concerning exact origin of this type of Choora...
