Exciting Vintage Mid Century Modernist Sterling Silver Ring Signed MK

Description

I have tried to find other rings by this
artist without success.  It has such a
bold mid century look!  I love the
combination of geometric shapes with
the color enhancements.  I do not
know what the green portion is.
If you recognize this artist please let me
know, thanks
Measurements in the photos
Has a wide band, I would call it a size
8 but you can look at the ring on the
sizer photos to make your own decisions
