Where are the large overhead retailers? Blue Nile, James Allen, Zales, Kay, and Jared each forbid us from listing their old-fashioned sites. Why? Likely because they sell a lot of the exact same diamonds for more money – same supplier, bigger overhead. The New York Times reported on studies we commissioned showed that many of the exact diamonds on Blue Nile and James Allen were listed on Rare Carat for 12-21% less (read the statistically significant 2018 studies conducted here and here).
