    I bought it for my son to give to my his fiance and we both did not expect the gems to be actually so tiny, but fortunately, the girl really liked it to be so delicate and she now wears it with pleasure. So it worked out well and we are all happy

    Got the ring yesterday and it is 100x smaller than what it looks like, the sapphire is so cloudy and looks green. When I got it the one of the sapphire gems was cracked and dented in. Not worth 175!!
