Professional Framework — Toward a Standard for the Characterization of the Physical Condition of Tribal and Indigenous Artwork
What does a condition grade actually tell you?
Sometimes a grade rests on direct examination supported by imaging and materials analysis. Sometimes it rests on a photograph. On the page, the two look identical. And for Tribal and Indigenous artwork, condition resists ordinary grading in the first place: erosion, wear, indigenous repair, ritual accretion, and archaeological weathering may function as evidence of authentic use rather than as damage—and may raise value rather than reduce it.
This article proposes a six-grade scale for African, Oceanic, Native American, and Pre-Columbian material, paired with four evidence tiers—direct examination, imaging, materials characterization, and dating—and three confidence levels that disclose what each grade actually rests on. It addresses deceptive alterations and fraud indicators, historic pesticide contamination, consent requirements that constrain examination, and why condition adjustments to value are derived from comparables rather than read mechanically off a grade.
Whether you are a conservator, collection manager, appraiser, insurer, attorney, or fiduciary, this article offers a common vocabulary for describing condition consistently across reports, loans, surveys, and litigation—and it is offered as a working proposal for professional discussion, calibration, and refinement.
