Vintage Pin/Pendant and chain

This fantastic Blue Gem turquoise (Nevada) on it's hand made chain just became available. C 1955 these pieces are true Thunderbird design and craftsmanship. 
The pendant is 2 inches in diameter and the chain is 17 inches long. The pendant can be removed and worn as a pin and the chain worn by itself. I always loved the chains with stones on them, inspired design.
