That's actually his middle name. His full name is Steven Quartz Universe and I believe that his father "Greg" had given him the name Steven and also his middle name "Quartz" since that's the last name of Steven's mother "Roses Quartz" and also for the fact that Steven's mother had sacrificed her body to give birth to Steven. The last name of Steven's father is "Universe" which is Steven's last name. Also when couples go from just being couples to being husband and wife, the wife get's her husband's last name and their children do as well.
