Kyma, the Greek word for wave. The band rises and dips in one continuous curve, seating a round lab grown diamond low against the finger, where it stays out of the way of everything you do with your hands. We cast it in 10k yellow gold, the hardest gold we work and the one we trust most for rings that never come off. Nickel free, hypoallergenic, and set by hand at our Athens bench.
