Vintage sterling coral jasper dots design clip earrings modernist designer

Stunning vintage sterling agate? coral ? or possibly orange jasper? dots design earrings. very modernist designer style... there is one specific dots designer that I think of when I see these.. Hardy of course. There is a tiny maker mark above the 925 mark... But it's too tiny for me to make out. In great vintage previous owned condition. no flaws that I can see. the clips are strong and have great tension. I'm not 100% what the stone is. I got them at an estate sale and the lady thought they where jasper. but to me they look more like a coral color agate. But selling them as a lovely coral orange stone 😊
