Five rows of stone run on the diagonal across a rounded 18k band, alternating white and green, each one channel set between two walls of gold so the colour reads as a stripe rather than as separate stones.
Eighteen karat is a deeper, warmer yellow than most vintage gold, and it drives the emeralds toward black-green and the diamonds toward stark white. Whether the stones mean something to you or you are just after some interest in your stack, she is perfect.
