1743 silver necklace?

Hello!I recently came across an interesting piece,wich has puzzled me because of it’s possible origin
What I can 100%tell you that the piece is sterling and has been tested
Now on to the interstig part,I asked a friend who speaks arab to translate for me,and he was able to identify only the marking on the third photo being the year 1743.What do you guys think,is it an antique otoman necklace?

I notice that you now have an answer on another forum.

It appears to be Indian,but The writings on the hallmarks have not been ID yet,so I’m still researching
