Treat her to a september birthday surprise with this dramatic three-stone ring. Crafted in sterling silver, this striking design features a trio of lab-created bright blue sapphires - the largest a 6. 0mm stone - set diagonally across the style. Polished and shimmering lab-created white sapphire-lined ribbons form the ring's open bypassing shank. Buffed to a brilliant luster, this pretty look adds interest to any attire.
