I absolutely love these knobs.  They are over sized and great quality.  I definitely would compare the glimmer to any true crystal knob.  The only reason I gave it 4 stars instead of 5 is that the screws are metric and the ones that come with the knobs are not long enough for drawers.  I have had to make 3 trips to different hardware stores because they do not carry or carry a limited supply of metric screws.
