Vintage exotic handmade tribal earrings, Crescent Moon w glowing blue art glass

Vintage exotic earrings. With blue inserts that glow like Abalone / Paua shells. Likely art glass. Handmade. The Moon Crescent parts are decorated with what looks like First Nations Haida art and also some other traditional totem style art works. 1.5" long. One blue insert has what looks like a tiny hairline fracture going across, as pictured. But it is so faint, that one can only see it with a magnifying glass. The x20 magnification picture of it is provided. The metal is silver tone, not stamped. So could be silver plated, or pewter.
