Yeah I think from India also. Awesome findlooks to me to be possibly indain (the country) made similar to a gorget type necklace item ---
I have a similar piece, but smaller I was thinking was marked 800, but I guess it's unmarked also. I do believe many pieces of 80% silver may come from places in North Africa like Tunisia.Sometimes they are 800 silver. This looks like the right color to be just that.
