Is there any evidence of wear?
It
looks "sun-purpled" with age, but I'm aware that that was an effect that was popular at one time and some unscrupulous folk deliberately accelerated the process; (I think it was in America, where they had access to rooftops for laying stuff out and the opportunity to be given a LOT of exposure to excessive sunshine;

)
There are "fakes" out there.
Having said that, this does look to be an old sort of thing. Possibly some fancy barware or something for pickles?
Something that might require tiny forks or cocktail sticks and somewhere to present them or dispose of them?
