Navajo Cross Necklace with Turquoise

Beautifully designed Navajo turquoise necklace in the form of a cross with radiant extensions. The cross has 6 rectangular stones. The cross is 3 3/8″ by 2 3/8″ including the loop at the top of the cross. It comes with a hand made sterling link chain. The chain is 11″ times two. It is not signed. I would date it to about the 1950s or 60s.
