Cluster jewel
Cluster jewels are a type of jewels that can be socketed in the outermost sockets of the passive skill tree (known as Large Jewel Sockets). These jewels extend the skill tree by creating new clusters of nodes, which can contain small nodes, notable skills, and even keystones. They can also create more jewel sockets (Medium or Small Jewel Sockets) which can support smaller cluster jewels. They are occasionally dropped from Delirium encounters or rewards.
Cluster jewels can be crafted to modify their properties. Like all jewels, rare cluster jewels can have a maximum of four affixes.
Mechanics
Non-unique Cluster Jewels come with two enchantments: one that determines how many passive skills are in the cluster, and one that determines what bonuses the passives in the jewel give. The latter determines what kind of mods the Cluster Jewel can roll. Like other jewels, they can have up to four explicit modifiers. The explicit mods will either modify or add bonuses to the small passives or add a notable skill to the cluster. Unlike other jewels, normal rarity Cluster Jewels can drop. Medium and Large Cluster Jewels have a third enchantment that determines how many jewel sockets it has.
Jewel sockets in the cluster can support either regular or Abyss jewels or smaller-sized cluster jewels. Medium Jewel Sockets in a

Added passives do not interact with jewel radiuses. Right click to remove from the Socket.. You can have a maximum of two sockets for Large and one for Medium.
Passives in the Cluster Jewel are never considered to be within radius of Jewels for unique Jewels which interact with nearby passives. Similarly, jewels with a radius have radius effects disabled if they're socketed in a Cluster Jewel jewel socket.
The passive points spent on the Cluster Jewel passives can be refunded by simply unsocketing the jewel, which refunds all passive points spent on that jewel's cluster. However, if a jewel socket or Keystone passive has been allocated, it will cost 1 refund point to unsocket it.
No jewel will have more than one of a given notable, but duplicates of the same notable skills can be stacked. If the notable has a limit to its effect, such as Purposeful Harbinger, that limit applies across all instances of the notable.
Selling 5 of the same kind(e.g. Large and Rare) will give you a new jewel of the same size and rarity. The new jewel will have the minimum item level from the 5 components, a new enchantment and new modifiers.

Optimal passive skill amounts
Since Cluster Jewels are able to have significantly varying amounts of passive skills, some of them are strictly better than others when it comes to optimizing for the most notable passive skills and Jewel Sockets using the least possible amount of points on the tree. This table details how many passive points need to be spent to allocate all possible notable and jewel sockets (referred to as "significant nodes" in the table) for every size variation of non-Unique Cluster Jewel base types. The jewel sizes with optimal pathing add 2, 4, 5, or 8 passive skills.

Regarding notable placements on Large Cluster Jewels, the notable mod that's listed second on the cluster jewel's mod list will be the one that's placed behind the jewel sockets. With three notable mods, which notable mod is second on the list depends on the combination of mods; the order is always the same for each set of notables. This is relevant for if you want to only use two out of three notables to get an optimal path of 5 passive skill points of 2 notables and 2 jewel sockets.
