"Diamond Crowned Queen" received mixed reviews from music critics on its release. Lyndsey Parker listed it as one of the eight listenable singles by a RuPaul's Drag Race contestant, describing it as "a deliciously trashy track". Comparing the song to The Normal's "Warm Leatherette" (1978), Parker wrote that "Diamond Crowned Queen" contained elements of "'70s sleazefeasts [...] '80s industrial, and mid-'90s house music". It was also positively received by Anneliese Cooper, who said it left her "gagging" noting its lyrics "will win my heart, every time". Patrick of Homorazzi.com described the song's chorus as "[d]irty and hot". While writing for Yahoo! Music, Parker included the single on her list of the seven "actually great singles" by RuPaul's Drag Race contestants. She described it as one of eight "listenable" singles released by the show's participants. FemaleFirst's Daniel Falconer agreed with Parker, placing the song on his list of the best music to come out of the reality television show.
