Absolutely stunning 925 sterling silver lab created blue tanzanite CZ wide band ring size 8 in excellent condition no signs of wear and is marked 925 china ( just an FYI anytime I see jewelry that is Mark China I am very skeptical that it is genuine sterling silver this ring has passed the magnet test an acid test and is genuine sterling) the band is 1" (widest part) please contact me if you have any questions thank you
