Era 1955 or Earlier  This is a really solid well made hand made piece with a great piece of shiny natural Manassa Turquoise in the center of the Naja. Unsigned Navajo or Apache Naja measures 2.39" wide and 2.80" high, and this is heavy    The necklace measures a nice and long 24" in wearable length, and it weighs a whopping 91.4 grams.  Not a speck of damage or repair marks, and this is ready to wear, and to show off.  lol!  The wire which the beads are strung on, is a little bent and curls up, but this is nothing and it will hang fine on the neck, with this heavy pendant. We can restring it for a fee. (This piece is at a photoshoot and will not ship untill on or after 11/11/22)
