Hey all, I found this store on Etsy that I really like. There are two choices for necklaces with the same look. My main concern is getting them something they'll enjoy wearing again. There are 10 girls to buy for (only two are standing up there in the wedding; the others are coming to a lunch on Friday and getting bridesmaids' gifts and hanging out with me while I get ready). So the $10 difference between these is going to be $100.

This necklace is ten dollars more than this very similar one, but has nicer materials. Is it worth the $10, jewelry experts? How is it only a $10 difference? My main concern is "gold-filled" versus "gold plated," but a recent Google search uncovered that my every day Kate Spade pendant is on a gold-plated chain! So I'm just totally lost now.
