I just bought a malleable spoon with a clear green round "stone" at the other end. It is very simple in design where the scoop is round and deep. It is also quite heavy, although small in size.
What sort of metal is used here? Is it an antique spoon? Which century? It has an EA marking behind the base of the scoop.

One heavy and malleable metal is lead.
That would probably mean it's an antique, since we all know now that lead leaches into the food or drink and shouldn't be used for eating utensils.
Take it to an antique shop to get an idea of it's origin before you research the hallmark. There are too many choices.
