Mineral Index Deck · Quiet Geometry is a curated card collection prepared for the Collectorium T launch selection. The series was designed as a complete visual index rather than a single hero card; sequence and consistency are central to the set.

Its visual identity combines letterpress card stock in a cloth folio, a black, copper and pale gray palette, and a folding folio holding four rows of cards. Recorded display dimensions are 63-card set; 8.8 × 6.3 cm each. The gallery documents gentle handling wear with no structural loss; one invented geometric maker symbol; no readable lettering. Each image is a separately composed camera view of the same presentation piece. This presentation record is informational only; ownership, maker attribution, certification, scarcity and provenance verification are outside its scope.
