Vintage mid century modern swirls of colorful enamel on copper pendant necklace pink green

Vintage mid century modern swirl colorful enamel on copper pendant necklace pink green.

Super cool pendant with a great design, the colors are so vibrant they look multi dimensional. The back of this pendant is signed but most of it has worn off so I cannot make out who the artist is. Approximately 18 inch goldtone chain.
Please see photos for approximate measurements.
