Azure Plagioclase was made infamous in the melancholic song prose Miner Blues by the Gallentean folk singer Jaroud Dertier three decades ago.

Plagioclase is not amongst the most valuable ore types around, but it has the largest amount of pyerite of any ore and is thus always in constant demand. It also yields some tritanium and mexallon. It requires 333 ore units to refine.
