Looks more Balkan, a Karakulak (Black Horn) Yataghan, the black sea ones have pointy forked 'horns' on the grip and an exaggerated curve like these below. The balkan ones tend to have integral bolsters, Turkish ones usually have the sheet metal ones.

Yours is a nice one, wherever it comes from. I prefer the lean mean fighters above the ornate bejewelled ivory ones.

The cartouche might help pin it down for those who cn recognise or translate it.
