Swallow Enamel Brooch · Harbor Cut is a curated wearable jewelry object prepared for the Collectorium T launch selection. Designed as a close-view piece, its geometry changes subtly with movement while the setting keeps the materials visually distinct.

Its visual identity combines sterling silver, vitreous enamel and glass cabochon, a deep blue, ivory and silver palette, and a small radial composition with a secure pin back. Recorded display dimensions are pendant 6.1 × 2.4 cm. The gallery documents honest age-consistent wear, photographed without cosmetic concealment; 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.
