in 2010 everyone should be use grade a cz 's for these type of fake ring ... . i have all kind of fake cz jewelry and this ring obviously look fake . there be some great grade a cz ring on ebay if you guy want something that truly sparkle like the real thing ... i put this ring next to one of those and it do not even come close ... . . it be a nice little ring , but you can get better for less money ... if you know anything about diamond this one obviously look fake and be less brilliant than the picture show
