This modern cocktail ring contains a .50 carat round brilliant cut diamond with VS2 clarity and K color grading set in 18 karat yellow gold. The diamond sits in a bezel setting that frames the stone completely around its circumference. What makes this piece unusual is its rectangular shape and functional sliding diamond feature that allows the center stone to move back and forth as the wearer moves their hand. This movement creates a dynamic visual effect that changes as the ring is worn throughout the day.
