Cluster Gems

"These were Crystal Gems, shattered into pieces. They were buried together.-" "The Cluster" is a fusion of former Crystal Gems. It first appeared "Keeping it Together". It was made by forcing Gem Shards of fallen Crystal Gems together through unknown means.

Appearance
The Cluster appears to be comprised entirely of limbs conjoined together in a single body, wrapped in a grey cloth. At its core, the fusion is comprised of four different shattered Gem Shards that are physically fused together. It possesses four, large eyes. The Clusters' irises and visible Gem Shards are green, yellow, blue, and purple.

"Jail Break"
When Peridot and Jasper are at Sapphire's prison, Peridot says, "We can't leave yet! The whole point of coming here was to check on the Cluster!".

"Keeping it Together"
The appearance of the Cluster was so horrifying to Garnet that she became unstable to the point where she almost defused. It is for this reason that Ruby believes the Cluster was created as punishment by the Homeworld for the Rebellion. It was eventually "poofed" by Garnet and is current resting within one of her bubbles in The Burning Room with the other fusion experiments.

Trivia

 * The Cluster is the first forced fusion in the series.
 * The Cluster is the first fusion to never speak in the series; the second being Rainbow Quartz.
 * The blue "leg" off to the left appears to have the same boots as Amethyst and Ruby.
 * The silhouettes of the Cluster members have traits similar to other gems on the show, most obviously Pearl's "Pilot" hairstyle.
 * It should be noted that when the Gem fusion's body silhouette appears, each "body" seems to have a similar body type, and hair style, implying that the attempted forced fusion may have been somewhat successful, before they reformed into a limb-comprised hand.
 * When the Cluster's bubbled gem was sent back to the The Burning Room, its gem reshaped itself to appear like the Centipeetle Mother's gem.

Cultural References

Gemology

 * A Cluster of gemstones is a result of gems that fuse together due to extensive pressure from being underground. In most cases clusters are usually fusions of the same gemstone, however in very rare cases it is possible for clusters to form from different gemstones.
