Diamondsandrubies (foaled 30 April 2012) is an Irish Thoroughbred racehorse and broodmare. After failing to win on her only start as a two-year-old in 2014 she improved to become a top-class performer in the following year. She won a minor race on her seasonal debut and went on to win the Cheshire Oaks before finishing an unlucky fourth in the Epsom Oaks. She recorded her biggest success on her next start when she took the Group 1 Pretty Polly Stakes, but failed to reproduce that form in three subsequent races and was retired from the track at the end of the year.
