French Platinum 0.72ctw Single-Cut Diamond Eternity Ring
Twenty-four single-cut diamonds set in platinum, the French way. They called it an "alliance américaine" because the diamonds go all the way around—American excess meets French refinement. The engraving inside reads "3/31," no year specified, leaving us to wonder if it marked a Depression-era romance or post-war celebration. Single cuts catch light differently than modern brilliants—softer, warmer, like candlelight instead of LED. At 4.7 grams of platinum, this was built when wedding bands were expected to outlast empires. The band itself forms a continuous zigzag pattern, creating architectural interest between each four-prong setting—96 individual prongs, all set by hand without lasers or computer assistance, a level of labor that modern manufacturing abandoned decades ago.
