cff-version: 1.2.0 message: "If you use DiamondBench, please cite it as below." title: "DiamondBench: an open benchmark of AI answer-engine accuracy on diamond and gemology questions" abstract: >- 47 buyer-phrased diamond and gemology questions with a public, sourced answer key and a deterministic pass / partial / fail grading rule, for measuring how accurately AI answer engines respond to shoppers. Correct answers are drawn from independent authorities (GIA, IGI, the U.S. FTC Jewelry Guides, published gemology, documented advertising history). Grading is on verifiable gemology only, never brand preference.
