I am way unbder 50 and LOVE BOTH my studs and dangles!!!!!! Size Depends on the Woman I look awlful in biger ones. IMO they look fake on me sometimes duty requires me to wear the bigger ones but I am uncomfortable in them... I do not tend to wear anything bigger than a 9 mm if I can help it.

As for 7 mm set NO not fake just smaller.. there is a price jump so you will pay more, sometimes lots more for less a necklace verus a set...

How would she ware them? daily, Opera, Once in a while? what does she like? Is she a jeans and t-shirt gal or does she look fantastic 24/7? look at her existing jewelry does she like exact matching sets? same stone cut size etc.... or does she have pieces that all have the same gemstone in them??? It really does depend on the woman.

I agree with Zeide I have seen lots of Macys jewelry (at Macy's) and not impressed.. you are paying for naem not quality aas with most big name stores..... Chek out the vendors here.. is also a good Idea.. but honestly do you know she even likes pearls? Some women hate pearls..

Good Luck!
