Usually, princess cut earrings look bigger than the size but these, 5mm looks more like 4mm.  Look pretty small. But they're very pretty and classy.  I guess if they were any bigger, they might not be as classy and elegant as they are. But I was hoping they look at least 5mm.  So I'm giving them a 4 stars.

<update>
I actually like how small they are now.  They are perfect for work or job interviews...or those days when you're dressed to impress and don't want to take the attraction away from your beautiful dress or shirt you are wearing...I love them!
