Sterling and Turquoise Native American bird and butterfly Artist made

This comes in the box from the original gallery that it was purchased from in Wisconsin. Made of an unmarked Sterling Silver and genuine Turquoise , includes ring, and earrings that are the folded clip back style. It is obviously original and handmade, even the chain was made from individual wire, as well as the clasp was made by the artist. This is so rare to find an authentic piece still as a suite with all original pieces, there does seem to be a signature mark which is very hard to read. There are three Thunderbirds and two butterflies in the necklace, the ring is one butterfly and the earrings are two round medallions or flowers. Length of necklace 16.25" Earrings 3/4" inch wide, just shy of ring about 7/8" of an inch across
