In Path of Exile 2, few items capture the attention of players like the Heart of the Well Diamond. This Unique Jewel has quickly gained a reputation as one of the most valuable drops in the game, not because it's impossibly rare to find, but because its true worth lies in the potential locked inside its modifiers.

This guide breaks down everything you need to know about the Heart of the Well Diamond: where it comes from, how to shape it into the perfect version, and why it's considered a top-tier investment.
How to Obtain the Heart of the Well Diamond
Unlike some chase Uniques that require endless boss farming, the Heart of the Well Diamond has a clear, guaranteed source:
Drop Source: It only drops from Lichborn Exiles at level 48 or higher.
How to Encounter Lichborn Exiles:
Kill a Rogue Exile near an Abyssal Pit to spawn its corrupted version.
Explore Abyssal Depths or the Dark Domain in level 48+ maps.
Endgame Optimization: Once you reach maps, you can boost your odds by investing in the top section of the Atlas Passive Tree, which increases Rogue Exile spawn rates. The more Rogue Exiles you find, the more chances you have at fighting a Lichborn and securing this Jewel.
In other words, farming Lichborn Exiles becomes the core path to target-farm the Heart of the Well Diamond. For efficient farming, many players focus on juicing Abyss mechanics in their maps, stacking pack size, and chaining areas with Abyssal Depths.
Using the Heart of the Well Diamond
When this Jewel drops, it doesn't reveal its full power right away. Here's how the process works:
1.Unidentified Modifiers
Every Heart of the Well Diamond comes with four Desecrated Modifiers.
These modifiers are initially hidden and must be revealed.
2.Revealing at the Well of Souls
Take the Jewel to the Well of Souls in Path of Exile 2.
For each modifier, you'll see three possible choices, and you select the one you want.
3.Rerolling with Omen of Abyssal Echoes
Each modifier can be rerolled up to two times using Omen of Abyssal Echoes.
That means you can reroll the full set of modifiers twice, giving you multiple opportunities to craft your ideal setup.
Be aware: each reroll consumes an Omen, so you'll need four Omens to cover all modifiers in a single pass.
This process creates both excitement and tension. On one hand, you have agency over your choices. On the other, the reroll system tempts you to burn resources in pursuit of perfection.
Why the Heart of the Well Diamond is So Valuable
So what makes this Unique Jewel so special compared to regular rares?
1.Customizable Power
Unlike ordinary jewels, the Heart of the Well Diamond allows you to pick from three different modifiers per slot. That's a level of control most other POE 2 items don't offer.
2.Exclusive Modifier Pool
Some modifiers are completely unique to this Jewel, or they appear as stronger versions of standard affixes. That means you can create builds around options that simply don't exist anywhere else.
