Rock-slab carved HAPPY HALLOWEEN display

Monumental rock slabs carved into bold letters sit across a low chamber, the phrase "HAPPY HALLOWEEN" centered and commanding in a solemn, opulent mood with cool mystery. The carved letters are inlaid with raw amethyst geodes and polished orange calcite nodules, and the stone shows coarse grain, chipped faces, and glittering micro-facets inside crystals. Focus is shallow near the inlaid interiors so crystalline facets sparkle, while a subtle outline glow gives calm separation and a gentle, low-contrast grade casts cool-blue and warm-orange balance; amethyst purple and deep orange register as primary accents. A soft, low fog pools at the slab bases and thin dust motes float, with scattered crystalline chips and a small unadorned pedestal as props to suggest ritual use. The composition is full-frame 16:9, eye-level viewpoint, wide field of view that frames the carved phrase centrally with generous negative space above and clean dark edges for crop-safe poster use. On-image text appears exactly as "HAPPY HALLOWEEN" in all-caps, vertically centered across the slabs, large scale to fill the mid-frame, each inlay showing crystalline interior shine, and letters contrast strongly against charcoal stone with bright internal glow for legibility.
