I just got these today and while I am not expecting diamond-like brilliance in comparison to the ring I also ordered from Armour in the Amazon.com COLLECTION, these are somewhat embarrassingly dull.  However, I have costume jewelry from Avon with cubic zirconia's on them much duller and so this is not that big of deal to me.

I'd give it 4.5 stars BUT these appear very plastic-ky and not such great quality of cubic zirconia. While I was not expecting them to shine like moissanite or anything, they do seem to be ridicously "you-get-what-you-pay-for" (or less)looking so, be forewarned before buying that these do not sparkle very much at all! They, in fact,  look like very opaque plastic (yeah a lot of cz's have that look, I realize.) But since you cannot beat this price but do not expect them to look better than plastic/glass, because then if they do, you will be impressed, unlike myself who received 2 items of costume jewelry on the same day and the other was much better in quality (did not know that was possibly without using moissanite).
