The CJ is going to be very difficult to determine the artist, several different artists use this mark and the style of the ring is traditional. The Hopi piece possible could be made by Larry Pooyouma. Wright’s Hopi hallmark book has a very similar hallmark attributed to Larry, and many times a hallmark can have slight variations or change when a new one stamp is made. The sunface is a Hopi arts and crafts guild mark. Hope this helps.
Thank you Jason! Would you have any idea how old or the value of these? Especially the pendent I have tried to search this and haven’t found a design close to it. I think the bird is an eagle possibly?
