Kenneth Bitsie Native American Navajo Opal Coral Sterling 925 earrings Vintage

One of a kind earrings from Native American artist Kenneth Bitsie. Earrings have never been worn. Made of Sterling silver with opal and (I believe) coral inlay. Lovely colors together. I’ve had the earrings for some time and they are a bit tarnished. I received them from a family member as a gift after they visited a gallery in Arizona, but unfortunately I only wear studs so they were never worn. There is an indented spot in the coral on one of the earrings- see last photo. I think it’s just part of the natural variation of the material not a chip since they came this way, but pointing it out anyway.
