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. Create a square luxury jewelry campaign image with the exact requested word “Eternal” as the sole text, centered prominently and occupying most of the frame width. Preserve the word exactly, including its capitalization; do not add any other lettering, labels, or symbols. Let the gemstone-cut letters float in a jeweler’s vault of deep midnight navy fading to black, with generous dark negative space around them. A hard pinpoint spotlight from above catches the upper facets in near-white brilliance, while the lower facets fall into rich blue-violet shadow for crisp, dramatic contrast. Send a few precise prismatic rainbow beams outward from the brightest crown facets, and let delicate internal caustic corridors glimmer through the crystal. Add sharp six-point star flares at select letter peaks, bright enough to sparkle but not obscure the word. The composition feels enduring, refined, and intensely precious: immaculate crystal geometry suspended in darkness, with every reflection controlled and the lettering unmistakably legible.
