The cushion cut of these stones really catches the light!!  They have the perfect sizes to choose from.  I choose the 1ct.tw size, as I wear them right next to my main earring. I wear my Cz's when I travel/not to worry if one gets lost.  These, by far, are my new favorite!!  Might even purchase one of the larger ct.wt.  Easy to put on along with sturdy earring posts with a great butterfly back.
