Aventurine is a tall young man with fair skin, short dark blonde hair and bright, unnaturally colored eyes - blue and pink. His style traces the motifs of US men's fashion of the 1930s and 40s: classic light trousers and shoes, a formal vest, shirt, and coat with a fur collar. Sometimes wears a hat. On Aventurine’s hands you can see many rings and bracelets, as well as a long earring in his ear and pendants around his neck.
