I bought this tanzanite stone in Tanzania and had the sterling setting designed by a jeweler in the States. The stone is pretty much flush with the setting. The back part of the setting is open to let light in. The shank is rounded at the sides. The top of the ring measures a tad over 1/4" X 1/4". The ring size is 7. Inside the shank is stamped 925 with the designers initials. Excellent condition. The weight is 4.89 grams.
