carved from flawless gemstone crystal — each letterform cut with precision faceted geometry following brilliant-cut and emerald-cut diamond principles. Table facet, crown facets, girdle edge, pavilion facets all precisely rendered. Optically pure material: Brilliance (white light return), Fire (rainbow spectral dispersion), Scintillation (extreme facet contrast sparkle). Internal caustic corridors visible. Six-point sparkle flares at letter apexes. Maximum optical drama — every letter a dazzling cut precious gemstone. Portrait 3:4. Render the exact text “第二天行程” as the sole hero composition, stacked with measured breathing room and occupying the central 72% of the frame. Each character is carved from flawless optically pure gemstone crystal, with crisply engineered table planes, crown facets, razor-clean girdle edges, and deep pavilion cuts visible within the strokes. A deep midnight navy fading into near-black surrounds the characters like the darkness of a jeweler’s vault. One hard pinpoint spotlight from directly overhead ignites near-white brilliance across upper facets while lower planes fall into saturated blue-violet shadow. Internal caustic corridors travel through every crystalline character, refracting narrow spectral ribbons of cyan, violet, amber, and red onto the surrounding darkness. Sharp six-point star sparkle flares erupt at the highest corners and cut intersections, controlled and precious rather than scattered. The lettering appears to hover just above a black mirror surface, catching a restrained inverted glimmer beneath. Keep the frame immaculate, luxurious, and dramatic: a gemstone itinerary title with diamond-like optical fire and profound nocturnal contrast.
