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. CRYSTAL as precision diamond-cut letterforms centered at 78% frame width. Background: deep cobalt blue gradient fading to near-black at edges — jewel photography atmosphere. Single hard overhead pinpoint spot creating knife-edge facet contrast: illuminated crown facets burn near-white brilliant, shadowed pavilion facets recede into deep indigo-violet. Six-point star sparkle flares at every letter apex and major facet junction. Sharp prismatic rainbow beams scatter from crown facets — red, orange, yellow, green, blue, violet light rays cutting across the deep blue background. The letters read like a row of cut diamonds under gemological lighting — every polished plane visible, breathtaking spectral fire.
