Vintage 925 sterling silver Southwestern turquoise coral butterfly necklace

Vintage Native American sterling silver butterfly pendant. Handmade by either Navajo, or (most likely) Zuni. Inlaid with natural blue turquoise and natural red coral stones. The original chain broke, so I put it on a newer sterling silver chain that is 16" long and stamped 925, as pictured. The pendant is 0.75" (with bail) and I can't find the stamp (in the old days, they were not mandatory). But it was professionally tested as 925 sterling silver. These unique handmade pieces are now rare and collectible.
