Two rings that function as a set are two rings with a built-in styling answer: the 2mm polished band and the 4.3mm Greek key band stack with geometric harmony, the plain band providing negative space that makes the pattern of the Greek key read more clearly. The Greek key motif - a repeating right-angle spiral borrowed from classical architecture - brings history and pattern-design sophistication to a band format that might otherwise read as simple. In 18K yellow gold over sterling silver, the warm gold tone gives the pattern an additional richness. Wear as a pair, or separate across different fingers for a layered approach across the hand.
