Shades of Blue

History's been changed, and as a result, a different human-Gem hybrid is born. Yamcha, the son of Holly Blue Agate, is raised by the last five Crystal Gems: Jasper, Peridot, Lapis Lazuli, Rose Quartz, and Apache Tears. As he grows, Yamcha learns more and more about not just Gems, but also his mother and who she really was (Half-Gem!Yamcha AU; Momswap AU)
