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 campaign image for the single word “GLASS,” centered prominently and spanning most of the canvas width. Keep every letter crisp, legible, and complete, with generous dark negative space around the word. Set it in a jeweler’s vault of deep midnight navy fading to near-black, with no visible room details or distracting props. A hard overhead pinpoint spotlight strikes the lettering, making its brightest facets burn near-white while opposing facets fall into deep blue-violet shadow. Let sharp six-point sparkle flares glint at the letter apexes, and send a few precise prismatic rainbow fire beams outward from the brightest crown facets. Subtle luminous caustic corridors travel within and between the letters, reinforcing their depth without obscuring the word. The lettering appears suspended against the darkness, with a restrained pool of reflected light beneath it and faint colored glints on the surrounding black surface. Preserve a clean, deliberate composition and a premium, dramatic finish; the text remains the unmistakable focal point.
