The Perfect Jeweller’s Orb and Greater Jeweller’s Orb in Path of Exile 2 both serve to add sockets to skill gems, but they matter most at different stages of build progression due to their specific effects and rarity.

The Greater Jeweller’s Orb adds an additional support gem socket to a skill gem that already has three sockets, upgrading it from a 3-link to a 4-link. This is a crucial early-to-mid endgame step, enabling significant boosts in skill power by allowing one extra support gem. Greater Jeweller’s Orbs are rare but more accessible than Perfect Jeweller’s Orbs and are typically farmed in high-tier maps with dense monster packs and league mechanics like Breach or Delirium. Because 4-linked skill gems mark a major power increase, these orbs are highly valued for transitioning builds into strong late-game viability. Efficient farming of Greater Jeweller’s Orbs can also benefit from strategies involving poe 2 currency for sale to aid in trading when direct farming is slow.

The Perfect Jeweller’s Orb adds a fifth linked support socket to a skill gem that already has four sockets, taking it from a 4-link to a 5-link. This orb is far rarer and is the pinnacle for maximizing skill gem power and complexity. Its rarity and high value make it much harder to farm efficiently. It is best applied strategically to your most impactful, core skill gems to unlock the highest level of support synergy. Perfect Jeweller’s Orbs are typically farmed in very high-level maps (e.g., Tier 16) with heavy mob density and special farming modifiers to increase drop chance, or alternatively obtained through trading due to farming difficulty. Many players find that buying poe 2 currency enables smoother acquisition of these orbs through trade.

Key distinctions when each matters most:

Use Greater Jeweller’s Orbs primarily to move from 3-links to 4-links early in endgame, which unlocks a substantial power boost and is a prerequisite for reaching 5-links.

Use Perfect Jeweller’s Orbs once you have established strong 4-link skill gems and want to push your build to maximum potential by adding a fifth linked support gem, essential for top-tier endgame content.

In practice, the Greater Jeweller’s Orb is the foundation for strong builds, while the Perfect Jeweller’s Orb is the final refinement that unlocks maximum skill gem power and versatility.

Efficient farming and use:

Greater Jeweller’s Orbs are more commonly farmed in Tier 10+ maps focusing on Breach, Delirium leagues, and benefit from atlas passives like Local Knowledge.

Perfect Jeweller’s Orbs require farming in even higher-tier maps with optimized conditions (Tier 16, dense monster packs, best map mods) or buying via trade due to their extreme rarity.

Advanced users can multiply the value of a single Perfect Jeweller’s Orb through in-game mechanics to upgrade multiple 4-links to 5-links with one orb, but this requires precise timing and preparation.

Greater Jeweller’s Orbs matter most for upgrading and solidifying your skill gem links early in the endgame, while Perfect Jeweller’s Orbs matter most for maximizing and perfecting your build power at the highest levels of play. Both are essential, but their value and application reflect their rarity and the stage of build progression they cater to.
