Small studio vase with paua shell decoration

Small studio vase with paua shell decoration
Very odd
Sort of looks like a Raku fired pot but I’m not quite sure, kind of burnished look.
And has a resin bit on top with paua shell.
Impressed marK.
Presumably a tourist gift thing from New Zealand or somewhere.
Just an odd thing so wondered if anyone else had come across one - before it goes off to a new home.
