In short, Spirit Crystal is something that requires order to be born.
The source of Spirit Crystal is actually a harmless replication of the 'soul bricks' in the 'Deceased Monarch' by Adalbert.
The many souls composing the Deceased Monarch, their greatest function, is to construct the Sublimation Structure of the Deceased Monarch itself, providing powerful computational ability that allows the Deceased Monarch to sublimate, achieving effects similar to the 'Top Seat's Blood'.
Adalbert didn't intend to accomplish everything at once, so he removed all complex requirements and directly designed the Spirit Crystal as an entity capable of linking directly to the Heart of Terra with computational ability. High purity Origin Quality is its material base and basic value source, while its face value is the most expensive 'distribution of computational power' that is both priceless and cheap.
