Update 12.22.2016:  its been over 5 years (maybe 6 or 7) That i have had these rings and they have not tarnished, stones are still intact, and the rings sparkle like the first time i saw them. One of the best buys I've made off of Amazon.
Original review:
 i ordered this ring set about a month and a half ago and rec'd them end of october.  the minute i opened the box and slipped them out of the pouch, i was in love :p  these rings are well made, sparkle like crazy and look very passable as the real thing.  i have worn them all the time since then from doing the dishes, gardening, kneading dough, you name it.  they are still as lovely as the day i rec'd them.  the size runs true and for the price, this deal cannot be beat.
