An authenticity guide outlines the evidence collectors should evaluate to confirm that a piece of Native American jewelry is genuinely made by an enrolled Indian artisan and accurately represents tribal tradition. LomaSiiva’s specialists apply these criteria when assessing each item in our collection.
Artist Signature
The handwritten or stamped mark placed by the maker, often accompanied by a tribal affiliation or studio name. Recognizing an artist’s signature helps distinguish original work from imitations.
Certificate of Authenticity
A document issued by the artist, tribe, or a reputable organization that records provenance, materials, and maker identification. While valuable, a certificate alone does not prove authenticity without supporting evidence.
Hallmark
The official stamp indicating metal purity, such as ".925" for sterling silver, and sometimes a tribal emblem. Hallmarks verify that the metal meets legal standards but say nothing about the maker.
Indian Arts and Crafts Act (IACA)
U.S. law that prohibits the misrepresentation of goods as "Indian made" unless they are produced by a member of a federally recognized tribe. Compliance with the IACA is a baseline authenticity requirement.
Material Analysis
Scientific testing of metals and stones, including X‑ray fluorescence or microscopy, to confirm composition and identify treatments. Genuine pieces typically use natural turquoise, coral, or other stones sourced from documented mines.
Provenance
The documented history of ownership and origin, often traced through gallery records, exhibition catalogs, or family heirloom stories. Strong provenance supports the piece’s legitimacy.
Reproduction
Modern replicas that imitate traditional designs but are manufactured in bulk, often overseas. Reproductions may use lower‑grade materials and lack artist signatures or hallmarks.
Stylistic Consistency
The alignment of design elements—such as traditional motifs, carving techniques, and setting styles—with the known work of a specific tribe or artist. Inconsistencies can signal a non‑authentic piece.
Verification Process
A systematic review that combines signature inspection, hallmark verification, provenance research, material testing, and compliance with the IACA. LomaSiiva follows this multi‑step process for every item.
