Vintage 14K Yellow Gold Ivory Bone Hoop Earrings 7/8”

Vintage 14K Yellow Gold Ivory Bone Hoop Earrings 7/8” These are an interesting pair.. the gold wire is 14K yellow gold. The posts and the backings are however sterling silver with gold plating AND these are oddly marked 925. Which, they should be marked 585. I was able to scratch the wires and confirm 14K yellow gold and posts as sterling with gold overlay. Measurements 7/8 inch x 7/8 inch
