Egyptian Revival collar necklace & earrings, Vintage 80s

Unbranded, purchased at a museum shop in the mid-80s. I believe the red beads are glass and the black ones are glazed terra-cotta. The earrings appear to be made from natural brass, whereas the necklace contains silver tone metal. The earrings had small areas of tarnish, which I carefully cleaned with mild soapy water, not wanting to disturb the patina. Then I finished cleaning the residual tarnish with a jewelers cloth. Although this set is not fine jewelry by any means, there is a tremendous amount of painstaking labor invested in its creation. The beads appear to be handmade; provenance might be determined by someone knowledgeable. This set definitely has an ethnic edge, with a design inspired by ancient Egyptian culture. May even be categorized as Boho or hippie today. From my well cared for personal collection. Please feel free to ask questions or make an offer, thank you!
