mid-century modern vintage ceramic wall pocket vase jade green shell Haeger pottery?

Mid-century mod vintage wall pocket vase, a shell or just deco style 'swoop'? Lovely jade green color!

There's stilt marks on the back, but no makers marks on this piece - I was told it's Haeger pottery (which is generally marked with a label, so that does make sense to me).

Nice and clean inside and out. This has a few tiny glaze chips, no other damage.
