Diamond Tiara is generally depicted as being rude, shallow, stuck up, sarcastic and nasty. Her closest (if not only) friend appears to be Silver Spoon, who often acts as a follower and is usually seen by her side. She sees those without their cutie marks as inferior and tauntingly refers to them as "blank flanks". Despite the Cutie Mark Crusaders often being the subject of her ridicule, she will try to "befriend" them if something is in it for her, as seen in Twilight Time. She also encourages their stories in Ponyville Confidential but later resorts to blackmailing them.
