We caught up with our friends at RockHer, the first-ever artificial intelligence-driven bespoke luxury engagement ring site and direct-to-consumer brand with the world’s first diamond search engine (pretty intense, right?), and they really magnified the reasons why getting a diamond that’s not just “right,” but “right for you” is so important. ... The coolest part of their whole business is what they do with a little thing they call ROSI. They’ve come up with the world’s first digital diamond expert / gemologist, who is ONLY there to make sure you find the best diamond for your partner. It starts with an algorithm, gets enhanced through IBM’s Watson artificial intelligence, and results in a killer new shopping experience. For real, engagement ring and diamond buying as we know it will never be the same.
