Vintage navajo signed Royston turquoise sterling silver feathers necklace 60's

Absolutely AMAZING no words! I've had this a while now and haven't listed it because I've forgotten who the previous estate owner said this was signed by, it's very old so the signature isn't as clear, it's signed on the back of all 8 sterling feathers! Each one signed. Take a look at the 3rd photo and see the BEAUTIFUL AMAZING colors in the blue green turquoise stones! the stones have sterling silver beads in between here and there. This has the older hand made sterling clasp as well. This is definitely a one of a kind you are NOT likely to see again! I've looked for a long time now and can't find anything similar. This has good weight to it, I can weigh when I get a new scale, measures- 26" long feathers measures- 1.75" long almost 2" each! Reminds me of the squash blossom design this is just feathers instead.
