Note: For this chapter many Carbons will be talking so I will refer to them as Carbon1, Carbon2, etc. This will be how I do conversations for them until I can come up with names or something.
"So you are a diamond?" Peridot 6R9D asked. "But you are a fusion of Carbons?"
"Yes" Carbon1 said. "We can also fuse into different gems."
"How do you know?"
"No idea, but we all just sorta know." Carbon2 said.
"I need to bring you all to the Diamonds."
After calling for a transport to take them all to the Diamonds, peridot noticed a new gem and four missing Carbons. The new gem looked similar to an Agate with Lapis Lazuli like hair.
"You fused?" She said.
"Yes we did" The new gem replied. "I am Beta Graphite"
"Alrighty, let me get you register" Peridot muttered. "Name is Beta Graphite, weapon?"
"None." BG said "Just shapeshifting."
"Okay, you are a fusion so you don't get a cut or facet… Ugh! Why am I even doing this? We don't catalog fusions. And you all came from the same hole so you are all technically the same cut and facet! I'll need to come up with an entirely new category system just for you!
"Sorry." BG muttered.
At this point a call comes in from Yellow Diamond's Pearl, wishing to speak with the Peridot who oversaw SD3.
"Peridot, Facet: 6R9D Cut: 9RM here."
"Report in on what happened with the SD3 experiment."
Peridot explains how the Carbons came into existence to YD's Pearl while her transport flies across homeworld. She is told that the Carbons will have a private meeting with the Diamonds and should remain unseen by other gems until then. Peridot is instructed that she and the pilot nephrite should not talk to anyone about the Carbons until they are told they can.
The transport lands next to the diamond meeting hall, all three Diamond's ships floated in the sky. Peridot told the carbons to fuse and then walk into the building. Synthetic Diamond pushed open the doors of the meeting hall and walked in, they shut behind her.
"Well well well." Yellow Diamond scowled "What have we here?"
"I am Synthetic diamond." SD answered. "I am a fusion of the Carbons."
"The who?"
Synthetic Diamond unfuses into the twenty carbons.
"Us." They all say in unison.
Sorry that it is kinda short, it just seemed a good place to stop, given what the next chapter is going to be about.
