Can anyone help me identify the mark on these earrings?

I have these earrings that I think are red coral and sterling silver. The only mark on them is what looks like a 6 or a 9 or a feather. Can anyone tell me if these are Navajo and who the artist is? Thank you!

These earrings look to be Navajo. I don’t think the number has anything to do with the artist. Your chance of figuring this out is going to go through the seller. Good luck.
