24-karat gold metallic surface — three-tone spectral gradient: deep amber-brown in shadow recesses, rich warm gold on lit faces, razor-thin champagne-white specular lines where direct light strikes. Single hard key light from upper-left at 45°, casting crisp directional shadows to lower-right. Background: near-black with faint warm amber ambient glow. No colored tints — pure dark void that forces the gold to own all luminosity in the frame. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the 24-karat gold metal, the hard directional key light and the dark void. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as bold 3D-extruded 24-karat gold with deep amber shadow recesses, rich warm gold faces and razor champagne-white speculars. COLOR PRIORITY: keep the font's own colors if specified; otherwise the warm amber-to-champagne gold range on a near-black ground. The rendered text "70" dominates the frame as monumental polished 24-karat gold numerals, with substantial dimensional depth and crisp beveled contours. Each visible face carries a three-tone metallic spectrum: rich warm gold across illuminated planes, deep amber-brown within inner curves, extrusion walls, and occluded recesses, and razor-thin champagne-white mirror highlights tracing the bevels where direct light strikes. A single hard key light arrives from the upper-left at 45 degrees, creating sharply defined directional shadows that fall toward the lower-right and reveal the sculpted depth of both numerals. The surrounding field is a pure near-black void, with only a restrained, faint amber ambient bloom close to the gold edges; no colored haze, gray backdrop, or environmental scenery. Fine ray-traced reflections glide across the metal surface, while tight ambient occlusion darkens the contact zones and the narrow negative space inside the zero. A sparse trace of microscopic gold dust catches the key light near the outer contours. High-resolution studio product render, deep blacks, clean silhouette separation, hard-edged shadow geometry, controlled reflective highlights, no additional words, symbols, or objects.
