I need assistance in identifying the artist associated with a leaf ( or possibly feather ) hallmark on the pictured necklace, pendant, earring set. It is sterling, red coral, opal, and turquoise. The pendant and both earrings are marked identically. It was purchased at a native American arts shop in Maine in the late 80s / early 90s I believe. Any assistance would be appreciated. Thanks.
Regards,
Bill
