Create a finished, modern boutique storefront sign in a wide 16:9 composition, viewed nearly straight-on so every letter reads clearly from the street. The sign is the hero: a long, slim, dark charcoal architectural panel mounted on a contemporary deep-navy stone storefront, with a fine brushed champagne-brass perimeter trim. Set the exact headline “13 CARATS” large and centered on the panel. Construct every character as a hollow neon tube: wide geometric sans-serif skeleton, flat terminals, generous open counters, uniform medium-width continuous strokes, and smooth rounded bends. No solid letter fill; each interior remains a deep dark void. The gas tube has a white-hot warm-amber center line, a vivid amber glow zone, and a soft halo extending farther outside each stroke than inside, with slight natural brightness variation along the tube. Below, set “FINE JEWELRY” in small, widely tracked, clean sans-serif capitals, then “GEMSTONES · GOLD · SILVER” as a finer third line. Render these supporting lines in restrained warm ivory lettering, clearly subordinate and sharply legible. Keep all three text strings exactly as supplied; do not add other lettering, symbols, logos, or prices. Include the storefront facade as a restrained scene element: dark mineral-textured stone, slim brass architectural reveals, a glimpse of softly lit glass at the sides, and a dark glossy pavement strip catching a faint amber reflection from the sign. Midnight navy and charcoal surroundings, subtle atmospheric scatter, no pure-black background. Frontal architectural photography, precise straight edges, realistic materials, ray-traced neon reflections, controlled bloom, high contrast, crisp sign typography, premium 8k finish.
