[Layout] The headline block sits in the upper left; the upper right features a single solitaire ring standing upright on a white cube pedestal, its round diamond at the top; the lower left foreground shows a pair of stacked pavé rings on a lower white slab. Generous negative space, products lit with cool studio light and soft cast shadows. [Subject] No people. Polished 18k-white-gold rings with brilliant-cut diamonds: the standing solitaire has a tall four-prong round stone catching a starburst sparkle; the foreground pair are crossover bands fully set with tiny pavé diamonds, one centered with a princess-cut stone, wet-look glints across the metal. Clean reflective edges on the geometric white podiums. [Headline] Upper left, spanning most of the width: "DIAMOND RING" in very large white high-contrast serif caps with wide letter spacing; below it two smaller white serif lines reading "The Gift" and "For True Love".
