Hi my friend,
As you said, you like "bling bling" things.
I have a good news and a bad news.
IMOH it is Ottoman. But most probably early 20th c. 1900-1920.
Like a lot of Indian and Persian daggers on this forum, and as you said, most probably decorative.
I don't want to say tourist item, but for sure some Europeans bought some of them as they are very decorative.
We have a full thread about your dagger but I cannot find it.
Your dagger is probably in tombak and the style is very much Ottoman Turkish.
Please look at similar items from the late 19th and early 20th.
