The Shoal Court

A really small-in-power court, managed by Turquoise Diamond. It takes care of Lapis Lazulis' management and delivery to every courts who needs one, two or even a dozen, as well as jobs for said terraformer gems, given to by Sea Peridot
The latter Gem can also give, through her Diamond, orders for maritime explorations, mostly taken care of by Malachite _{(A 'pure-breed' gem from a friend)} They also are in a competitive rivalry with the Inferno Court, considering itself superior that the tranquility of the other
Albeit less used for her actual purpose of entertainment, like Asthen Spinel for the Inferno Court, the Shoal Court also has its own Spinel : Axolotl Spinel ! Excelling in marine life's imitation and being able to talk with the fishes in Turquoise's aquariums, she's just a silly goober ! She's specifically good friends with Mermaid Lapis Lazuli, who's the main reason of why there's aquariums with organic critters : her lack of legs forces her to have a room of her own ... within water. The critters are just for not feeling alone-
We can also count Cellulite _{(who was 'artificially' created by Philosopher's Stone. A gem who was too ... slimy for the Court, not even wanting to ask them to join them ... but she decided to fully be included in Era 3)} in her ranks, but it will be for later.

The Diamond also have two Pearls as bodyguards : Mussel Pearl, who's her shield, and Murex Pearl, who's her sword. Both can also fuse for dealing with greater threats, forming Littoral Mega Pearl !
There is also Queen Conch Pearl's own little group, made possible because of Turquoise giving her the freedom she needed, as long as she stays affiliated to her Court. Which she swore, and is now a free Pearl ! She's always seen with her companion, Pink Coral, a non-binary scout ... quite efficient in their role of locating any threats ! Their alchemy is what people could say 'great friends' _{(literally, it's not a way to say they're both in love, okay-)}

On another side of the Shoal Court's palace is a cloistered place, where resides Cniradium, the medium of the court. Always meditating and rarely speaking, she is although guarded 24h/24 by Ammolite, a rather timid, ancient version of a Pearl. She might freak out around too many people, but when she needs to fight for protecting Cniradium, she'll lose any shyness and go for action ! Closeby, there's also the Court's Archives, taken care by Coral Mtorolite and assisted by Koi Pearl. The Archivist might look old, but don't get fooled : her 'data storage' will definitely not run out of space ! As for the Pearl, she might seem young and hot-headed, but she's an hardworking assistant !

Finally, there's a place even deeper in the Cloister of Cniradium, where resides Depth Sapphire, a Sapphire antagonized by many to be a monster of destruction because of her appearance, and Petrified Coral, the last member of her species, who were hunted for the perculiar way they act when shattered ... the Shoal Court brought them within Turquoise's ranks, due to her lax rule of appearances and 'illegal behaviors' _{(mostly fusion between two different gem types, mostly WIP)}. As a Sapphire, Depth might not properly see the future, but can ironically predict disasters in particular !
