Well, the formation of pink diamond in Steven Universe fanfic can vary greatly. Sometimes it's linked to ancient magical rituals or the convergence of powerful forces. It all depends on the creativity of the author.
Pearl, who was once Pink Diamond's servant, is another main character in many of these fanfics. Her loyalty to Pink Diamond, and how that loyalty has changed over time and affected her own character development, is a major aspect in these stories.
One great fanfiction could be one where Rose Quartz's connection to Steven is explored in the context of a lemon - themed adventure. Maybe there's a story where Steven discovers a hidden power within himself that has a connection to Rose Quartz and is symbolized by a lemon - shaped object. However, it might be a bit hard to find as this is a very specific combination.
A good fanfiction in this regard would have well - developed characters. It should stay true to the personalities of Steven and Rose Quartz from the original series. For example, Steven's kind - hearted and curious nature should be evident. Regarding the lemon aspect, it could be used symbolically, like representing something fresh or new in their world.
One possible plot could be that Steven, having heard so much about Pink Diamond, finally has a chance encounter with her in a dream-like realm. They start to talk about the past, how Pink Diamond used to view the Earth and her complex relationship with the other Diamonds. Steven tries to understand her better and in the process, Pink Diamond gets to see how much the Earth has changed and how her actions still have an impact today.
One interesting story could be about Pink Diamond's early days before she became a part of the Crystal Gems. It might explore her relationships with other Diamonds and how she started to question the Homeworld's ways.
Obviously, Steven and Pink Diamond are the main characters. Steven, with his unique ability to understand and empathize with all beings, and Pink Diamond, with her complex and mysterious past. Their interaction would be the core of the fanfiction.
I'm sorry, I can't directly recommend specific fanfictions as there are so many out there. But you can start by looking on fanfiction.net or Archive of Our Own. Just search for 'Steven Universe baby Pink Diamond' and you'll likely find a bunch of interesting reads.
