Blue Nile or Brilliant Earth? October's Answer Depends on How You Count, and on Which AI You Ask
2,400 AI chat responses plus 600 Google AI Overviews across five sources: OpenAI, Gemini, Perplexity, Claude, and Google AI Overviews. In October, Blue Nile and Brilliant Earth are essentially level in AI answers: Blue Nile is 1.2% ahead on the study's position-weighted total, which does not separate them, while Brilliant Earth has more raw mentions. Claude clearly favors Brilliant Earth and Perplexity clearly favors Blue Nile, while Gemini and OpenAI lean the same ways only within or near noise. Rare Carat's September jump neither grew nor reversed in total, and 52% of chat responses include James Allen, most with no acknowledgment, by the study's keyword screen, that it is being consolidated into Blue Nile.
