This elegant ring by David Yurman gives the illusion of a stack but it’s a single ring.

They note, “The DY Crossover® Collection explores the rhythmic weaving of line to create form and movement. Using a dynamic range of smooth and cabled cords, the individual strands are meticulously entwined.”

It uses sterling silver and 18k yellow gold, set with .14 carats of white diamonds. This retails for USD$995.
