Re. similarity between the example by Emanuel and mine ( #4, or the lowermost).
There was a suggestion, that the Emanuel's was decorated with Bidri. Don't know about his, but have doubts re. mine.
AFAIK, the objects to be decorated by Bidri are made of copper-zink alloy, then inlayed with silver and then their copper-zink background is blackened by a secret recipe. Thus, they are non-magnetic. I tested mine: strongly magnetic, i.e. iron , NOT copper-zink.
