Fusion Dance

"First you need a gem at the core of your being. Then you need a body that can turn into light. Then you need a partner you can trust with that light."

The "Fusion Dance" is a synchronized dance performed by two or more Gems in order to fuse into a Fusion Gem.

Generally, the dance is composed of the dance styles of the Gems that are going to fuse. Each dance is accompanied by a unique musical theme, usually exhibiting the motifs from the respective themes of the Gems. Fusion dances are only required by Gems of differing gemstones; Gems of the same type of gemstone can fuse at will.

Pearl and Amethyst
Pearl dances elegantly while Amethyst dances a bit more wildly, and the two run towards each other near the end. However, the only dance seen actually fails, and in both appearances by Opal, her successful dance is not actually shown. Their first successful dance was shown in "Log Date 7 15 2", this time without interuption. Their fusion theme is "Amalgam".

Garnet and Amethyst
Garnet begins by moving her hips provocatively, following it with some more sensual moves as Amethyst moves left to right. Garnet then walks forward as Amethyst rushes towards her, jumping into Garnet's pelvis, turning them into Sugilite. Their fusion theme is "Synchronize".

Pearl and Garnet
During their fusion dance, Pearl begins by twirling elegantly and then looking at Garnet sensually. Garnet's dance doesn't change much from her dance with Amethyst, the only difference being her movement is less aggressive and provocative and more sensual suiting Pearl's style more. Garnet and Pearl then walk towards each other while still doing elegant, yet sensual arm, leg, and hip movements. Afterwards they hold each other's arms while Garnet pulls Pearl down. Garnet then throws Pearl into the air and the fusion dance ends with Pearl twirling in the air and then free falling gracefully towards Garnet, forming Sardonyx. Their fusion theme is "Enticement".

Pearl and Rose Quartz
Rose picks the hem of her dress and sways it while Pearl twirls around elegantly, and the two come towards each other hand in hand and stare at each other. Then Pearl picks her legs up one by one and Rose holds Pearl's hand, and then the two stare at each other again. Rose holds Pearl as they turn around to the right and lastly both of them embrace, fusing into Rainbow Quartz. Their fusion theme is currently unknown, but the fusion dance takes place whilst Greg is playing "What Can I Do".

Pearl, Garnet, and Amethyst
While the dance itself isn't shown in the fusion's debut episode, part of it is shown in the game Attack the Light. The resulting fusion from this dance is Alexandrite. At the end of the short, Fusion, Garnet twirls Amethyst and Pearl with one hand each, and then fuse.

Lapis Lazuli and Jasper
Jasper grabs Lapis and twirls her, catching her and the two fuse into Malachite. Their fusion theme is "Collusion".

Ruby and Sapphire
While not technically a dance, Ruby grabs Sapphire by the waist, lifts her and the two spin for a while before they fuse together into Garnet. Their fusion themes are "Reunion" (in "Jail Break") and "Reconciliation" (in "Keystone Motel" and "The Answer").

Steven and Connie
Steven and Connie initially dance wildly and playfully until Steven trips and Connie grabs him. They look at each other for a while and, as they laugh, they fuse together into Stevonnie. Their fusion theme is "Alone Together".

Steven and Connie fuse again in "We Need to Talk", though to a song by The Philosophy Majors. This time, their dance is similar to Ruby and Sapphire's with them spinning while holding each other's hands.

This results in a special case, since Connie is fully human while Steven is only half-Gem, making the resulting fusion much more human-like than the others.

Garnet and Peridot
While they didn't actually fuse, Garnet and Peridot attempt to fuse in "Log Date 7 15 2" when Peridot tries to gain a better understanding of fusion with Garnet's assistance. Garnet grabs Peridots hands and twirls her so she is in her arms. Garnet then twirls Peridot and Peridot lets go, resulting in no fusion.

Trivia

 * The dance used to fuse is a mixture of both Gems' dancing styles, which are based on their personalities.
 * The "Fusion Dance" displayed by Gems is very similar to the Fusion Dance shown in the anime Dragon Ball Z. However, the Gems actually dance to fuse, rather than complete a set of poses like the Fusion Dance in Dragon Ball Z, in order to become one.
 * Some of the fusion themes' names correspond with combining or fusing.
 * Opal's is called "Amalgam", which is the combination of two elements to form another.
 * Sugilite's is called "Synchronize", which is to act as one, or in unison.
 * Malachite's is called "Collusion", which is when two parties conspire together.
 * Garnet's is called "Reunion", which is the act of reuniting.
 * Rainbow Quartz's is called "What Can I Do", which is like asking what she could do to improve the loving bond between the two.
 * Sardonyx's is called "Enticement", which is to attract someone or lure them in.
