Its a nice Indian Mughal style dagger. Copper kundan is known to be used instead of traditional gold. Jens is an expert in the field, and also has a fine copper kundan dagger, and perhaps will comment on. Also, the hilt contour (and color of jade, if the hilt is jade) does not match the scabbard throat, and could be not original to each other. The work on the scabbard... Asian(?), known to produce Mughal like hilts and daggers.
The writing on the box IMHO is not enough for claimed provenance without solid paper-based evidence. Are there any additional records to support a claim?
The box and pendant weaving do not look 19thC to me. The small red stone setting on the scabbard close-up, and "drilled" setting with missed gem on the hilt (and the hilt itself) seem to be off... just a few observations

Also, is there a photo of the blade?
