Zuni hallmarks
In Zuni hallmarks, small stone inlay, needlepoint and petit-point settings are useful construction descriptions, but they are not individual signatures.
Artist signature and construction
Look for Effie C. Zuni. Small stone inlay, needlepoint and petit-point settings are useful construction descriptions, but they are not individual signatures. Preserve the maker name on the reverse independently of the front design.
What to check next
Photograph the back of a pendant, buckle or cuff as well as its front. Keep the artist signature, any shop mark and the silver-standard wording together. Compare the exact mark arrangement with named artist examples.
