I got these because my birthstone is topaz and I also happened to like stud earrings.  These beauties are pleasing to look at with their shimmer and subtle brilliance.  It is also a PAIR - meaning both has same size and cut and looked just like pictured.  3.50 CTW is big, it's about 7mm and deceptingly huge to look at when worn.  Since I am not the kind to wear huge earrings so I gave it to my mom.  It looks great on her and she loved it.
