Black Diamond Authority

[ leader ]
 Black Diamond  
[ diamond color ]
You must wear a black diamond somewhere in you outfit!
[ location ]
You live in a ginormous ship that Black Diamond herself constructed. This ship is the soul and life of the Black Diamond Empire. We do not associate with the other Diamond Authority.
[ story ]
Black Diamond was part of the Diamond Authority, due to major disagreements and votes Black Diamond was to be banished from Homeworld. Little did the diamonds know but Black Diamond had been constructing a ginormous ship to harbor her black diamond followers. Not only was she able to carry all her followers (which isn't many) she also had a huge amount of space to hold more gems. She thought it through, she was to leave as soon as possible. At night, she got all her followers to enter the ship and out they flew. Homeworld had been searching for them ever since. Black Diamond knew she needed more gems, she needed more fighters. She began working on technology with her technicians. Eventually they created a pod that would create a gem using life source they would suck off from a random planet. After many failed gems, she managed to create her very first gem, Black Pearl. Black Diamond in joy loved her pearl, she treated her more as a right woman than a servant. However she still made sure Black Pearl knew her place and was only a Pearl. All of Black Diamond's followers loved her and practically worshiped her. Not all of them did, but most did. She then began created more gems and soon found it as an effective way. Not only would she be able to create gems, she would necessarily kill an entire planet to do so. However due to only sucking small amounts of life source from planet she really couldn't create more than 2 gems each trip. The failed gems were to either be bubbled, shattered, left behind, or even used as energy source which was the main go to.

Creating a Black Diamond Follower

[ gem type ]
 Must be a gem from grey to black color.
 It can be a multi-colored gem IF the gem is primarily black. 
        -Example: Snowflake Obsidian (Black and White gem, but mainly Black)
 The only exception for have a colored gem in the Black Diamond Authority is Diamond Swap. Meaning, if you were a Blue gem serving Blue Diamond, you are allowed to switch over to the Black Diamond Authority.
 Can be smooth, faceted
 Fusion allowed; Black Diamond herself thinks Fusion isn't just a fighting technique but she doesn't see any point in banning the use of fusion. Therefore Fusions are allowed.

[ story ]
 You have 3 options for a gem story:
 A gem who always followed Black Diamond and followed her in the escape from Homeworld in the Black Diamond Ship.
 A gem who followed another gem authority but switched over to Black Diamond in the escape of Homeworld.
 A gem created in Black Diamond's Resource Converter machine. If you do this story your gem has status choices.
        ➤ Successful Creation: A gem made from the Resource Converter successfully and now lives in the Black Diamond ship with a normal gem status.
        ➤ Failure Creation: Some failed gem creations from the Resource Converter are either left behind in another planet, killed, used as servants or their gem is used for ship energy.

[ appearance ]
 Hair: Any style of hair is allowed. But something that is highly recommended and used is the Straight Bangs cut on bangs, side hair, and/or the back hair.
        -Examples: Look at Harlequin Opal's bangs, Look at all of Black Star Sapphire's hair.
