Well, this looks like a Moro (southern Philippines) kris sword. The piece appears to be from the late 19th to early 20th century and from the pictures from the Maguindanao tribe. It is a datu piece (a chieftain) and may have originally been a junggayan type of kris. The hilt is made of woven silver and swassa (a type of 9k gold). A silver clamp is on the blade.
Now that all being said, the pommel is atypical and appears recent - later addition to the piece. It is made of ivory, the curve made of a boar's tusk. The stone at the top may be real but I suspect it is glass. Top and bottom of the pommel seems to be made of silver with little pieces of swassa.
Hope this helps and welcome to our little forum.
