Just a few comments/shots-in-the-dark ....
Your item appears to have a nickle-plated finish on its' handle , perhaps over brass .
Engravings appear to be rather primitive/semi-skilled too .
The main blade seems to have been hand-made , but shows little wear/signs of much sharpening .
My first & current impression is that it was made for the 'tourist trade' , perhaps middle-eastern/northern African origin .
The stones may or may not be rhinestones ... perhaps a trip to a friendly local jeweler might answer that one , malik .
