Pauline Rader stamped sunflower ring size 7- rare- only 4 ever made. 
This is a part of a very rare collection of Pauline Rader jewelry.  A very small collection was launched posthumously  based on her vintage drawings that were never produced.  
 
There were only 4 of these rings made, and no more will be manufactured. This comes from the family's personal  collection. This ring has a large bezel cut  smoky topaz crystal in the center.   This piece is stamped with the Pauline Rader logo.
