Golden Age Origin

Diamond Jack (last name never revealed) was given a ring with an inset magic diamond by an old magician. The magic diamond was later revealed to have been the lost eye-jewel of the god Khor from a temple in the Far East. The ring gave him the ability to create whatever he imagined and transmute objects. The ring also gave him super strength, invulnerability, super senses, the ability to heal others, limited flight, and a few other plot-convenient abilities. He used the magic ring to fight crime.


This Diamond Jack should not be confused with a card-themed supervillain who appeared in Captain Marvel Jr. #7
