Unmarked Earrings

I have a pair of earrings that I know nothing about. They are marked sterling, and with no other identity marks. They look to be very well made, are they real or fake, and who might have made them?

Hello, thanks for sharing. These are real earrings, looks like jet, turquoise, mother of pearl shell, coral and charolite. The style you think of as Zuni, but that is most likely Navajo inlay and made in one of the shops in town that do manufacturing.

Many thanks!
