Pearlescent Diamond

Pearlescent Diamond is a crafting material used for making Crystal weapons, armor, and ammo. It does not function as a standalone combat item; its value comes from being part of the Crystal equipment progression, where it serves as an ingredient for gear and ammunition tied to that set of crafts.

The material can only be obtained from Crystal Extraction Incursions, which makes it a reward that is directly tied to that activity. Because of that, players looking to build out Crystal gear need to focus on incursion runs rather than regular world gathering or ordinary enemy drops. This also means Pearlescent Diamond is naturally limited by how often Crystal Extraction Incursions can be completed, so it tends to be a progression resource rather than a common bulk material.

In practice, Pearlescent Diamond is best treated as a high-priority crafting resource. If you are planning to make Crystal weapons, armor, or ammo, it is worth saving these diamonds instead of spending them casually, since their source is restricted and their uses are centered on a specific equipment path.
