Vtg native style Goldstone blue silver beaded liquid silver necklace vintage

This was from an estate, I'm unsure if it's sterling or not, it looks amazing, but I'm unsure, this has beautiful dark blue sparkly Goldstone with turquoise and red AB glass stone crystals, and silver different shaped beads, then the liquid silver tube beads up to the barrel clasp. I don't see 925 sterling stamped anywhere.
