A single radiant-cut cubic zirconia stone is held upright at the center of this ring by four polished prongs, its clean rectangular facets catching the light from every angle. Below it, the sterling silver band splits into two slim strands that cross beneath the stone before rejoining into a smooth polished shank, giving the ring quiet movement without ever competing with the center stone. The result is a solitaire with a modern, sculptural edge — simple up top, unexpected underneath.
