Scandinavian modernist pendant

I bought this pendant some time ago on a flea market. I almost didn't take it with me because its not silver!
But then I took another look at it and I decided I would take it home.
I love the modernist style! I love the houses, furniture, jewelry... Lots of these designs are still modern today.
So after the 'art deco' period, now I'm more into a modernist period.
I didn't manage to collect much modernist jewelry though.
This pendant is about 5cm long in total.
I think its Scandinavian or maybe even German. It doesn't have any markings. The stone could be chrysoprase.
It seems one in a dozen, but you never know, so does anyone have an idea on the maker of this piece? Or even the county?
Thanks a lot!
