Is this Indo-Persian?

[Iliad]

Hi all, this is a recent purchase..........as you all know by now, I buy edged weapons because they look pretty, and then wonder what they are! The back edge for about 6 inches back from the tip is quite sharp; there are no markings at all on the blade; the silver scabbard has been mended in the centre section , with an inferior metal (it has a greenish tinge, so maybe some copper in there); the handgrip has panels of what I think is ivory. I took the sword to a silversmith and he tested the metal and confirmed that it is silver. Solid silver scabbard and silver on the grip indicates (to me anyway) that it must have been owned by someone of status. The ivory(?) panels are dark on one side of the grip and light on the other, and I am told that ivory exposed to the light remains light in color and ivory kept in the dark turns yellowish, hence my thought of ivory rather than bone or other.
All comments welcome, and thank you in advance.
