Vintage Southwestern sterling silver butterfly necklace. 

Butterfly pendant is inlaid with red and turquoise chip mosaic. It measures 1 7/8" by 1 1/2". It is not marked, so I acid tested it and the metal is sterling silver. 

The Necklace is strung with round and pinyone beads in silver. I acid tested them and they do have silver content, but not 925 sterling. The acid does not tellme mich about exact silver content, but I would guess 800. 

It is also strung with genuine turquoise nuggets and red coral ranches. Some of the coral is missing. Necklace is 27" long. Weight: 53.1 grams.
