Vintage Wolf Head retailer Silver & Amethyst Pendant

This is a signed (Alco, or Aloc, or Alcc) pendant designed in the 70's, Copyright 1974. It appears to be silver with a round amethyst. Sizes are as pictured,and includes and 18.5 inch chain. Very unique piece. I've researched it, and have not been able to find an exact match.

This pendant was purchased along with several other silver pieces at a high end retailer Estate Sale.
