TIKI Granite Head Olive Spoons?

Hope you can help identify these spoons (9 in total).

They look like Easter Island heads (Granite or Stone) all individually carved on unmarked solid silver (Acid tested) twist olive spoons

Obviously I am interested in their possible value, but I am also interested in where and when they were made (Possibly tourist pieces but just guessing)

I have not seen anything similar, and believe me I scour the internet daily.

Any help would be much appreciated.

Kind regards,
Mark

GRRRRR I can’t upload the photos no matter how small I make them, so please respond so I can send you photos separately.
