My husband bought me this ring when we got engaged last year. I loved it but it was too big, so I brought it to a local store for sizing, when they looked at it, one of the prongs wasnt even touching the ring. i checked with about 5 other places and none of them were willing to size it because of the liability of the stone possibly falling out. Therefore i've been wearing it with a sizer in for a year, I tried again today to get it sized, and it turns out it is a lab created diamond not a natural diamond! so its value is only about $450. Just a heads up! id ask before buying an item from this website.
