6.37 ct emerald lab diamond necklace in 18k yellow gold
fifteen emerald-cut lab diamonds arranged in a continuous horizontal line—geometry made visible. each stone is approximately 0.40 ct, set east-west in 18k yellow gold to emphasize width and architectural precision. step-cut facets create a hall-of-mirrors effect that demands clarity at every level. this is not subtle. the collective impact reads bold, modern, impossibly refined. paired with an azuki chain in 0.38 mm with adjustable slider clasp for a custom fit. 6.37 carats of pure geometry. hand-set by master jewelers in kofu.
