Standing and legal force
The FTC is a United States federal agency. Unlike the other three bodies recorded here, its jewellery naming and disclosure rules are legally enforceable: they are codified at 16 CFR Part 23 (Guides for the Jewelry, Precious Metals, and Pewter Industries), issued under 15 U.S.C. 45 and 46, current version 83 FR 40667 of 16 August 2018.
Scope of its naming system
Part 23 runs from §23.0 to §23.28 and is grouped by subject: §23.1–§23.11 general deception and precious metals, §23.12–§23.18 diamonds, §23.19–§23.23 pearls, §23.24–§23.28 coloured stones. Every clause opens with “It is unfair or deceptive to…”. This grouping matters when reading citations: a treatment-disclosure rule for a coloured stone lives at §23.24, not in the pearl range.
