Gold Earrings & Necklace Set

Hoop earrings from Blue Ruby (Aritzia). I can't recall where necklace was purchased but would be Holt's or also blue ruby. Necklace approximately 16" long and pendant 1/3". Tortoise shell resin material. Hoop diameter is approximately 1/2". Thin gold metallic with wrapped gold wire. Unsure of % gold content of either piece. Thanks for looking!
