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.
