The Leigh Anne Stack consists of 3 rings including one 2.5mm Taurus diamond channel ring in square, one 7mm silver densa ring in square, and one 2.5mm wide square band with 12 diamonds (The Zodiac Ring). Materials: Sterling silver (.925), oxidized sterling silver and lab-created diamonds. All materials are hypoallergenic. The black (oxidized) components of our jewelry will wear over time and eventually achieve a beautiful antique-like finish. This ring set was designed by Leigh Anne and then handmade in our Upstate New York production studio.
