Well, "Court Dagger" is not a defined form of a weapon ( like, for example, Flyssa or Kindjal). rather, it denotes a more sumptuous and decorative examle ( Like Kothimora Kukri).
I understand Yannis' point, but the main feature of a Yataghan is its blade: most often recurved ( with some "straight" exceptions) but always designed for cutting.
This one if a purely stabbing weapon. Thus, in my mind, it is not exactly a yataghan, handle notwithstanding. It is quite lavish and, taking into account the grossly non-standard blade ( trophy??? memento of a successful encounter???) I would be inclined to suggest more ceremonial, decorative function. True? False? Who knows.... This thingie is old and could have told us rather nasty campfire stories.
The "ears" are smaller that most, rounded and elongated: I wonder whether it hails from Greece. BTW, I love the old yellow color of the ivory!
And, as to the source of stones: there are plenty of arts and crafts shops that sell all kinds of stones and corals, very cheap. Check around: you must have one in your neck of the woods. In my small town ( ~125K) we have at least 2 that would supply corals of the needed size, form and color in 5 minutes flat. Atttaching them is easy: that was why God created "Gorilla Glue"
