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. Square 1:1. Crystals as precision gemstone-cut crystal letterforms centered at 78% frame width. Deep midnight navy-to-black gradient background — jeweler's vault darkness. Single hard overhead pinpoint spotlight: table facets burning near-white brilliant, pavilion facets receding deep blue-violet. Six-point star sparkle flares at each letter apex. Prismatic rainbow fire beams (red, orange, yellow, green, violet) radiating as sharp precise beams from crown facets. Internal caustic corridors glowing inside each letter. Letters float against the dark background like a row of cut diamonds — breathtaking spectral fire, Swarovski-quality brilliance.
