Diamond Gang

Silver Age
Carborundum Man appeared before the Union of Super Heroes to claim to use his brain to catch the elusive Diamond Gang. After studying information on the jewels the gang are made of (Ruby, Emerald, and Sapphire), he devised a plan to capture them at a sports stadium, using their psychological weaknesses: Emerald Man is green with envy, Ruby Man is easy to anger, and Sapphire Girl is sad ("blue") about being a criminal.

Renewal Notes
A number of Archie's Madhouse Comics (#27-47) were never registered with the US copyright office, nor did they include a correct copyright notice on their books. According to US copyright law, all works published between 1923-1977 that did not comply with copyright law became public domain upon publication. So, because the this issue had an incorrect notice, the characters featured in it fell into the public domain.
