Requesting some much needed jewelry opinions!
Below is a picture of the necklace I bought to wear on my wedding day. It's cubic zirconia but very pretty. I bought a pair of small cubic zirconia studs to wear for earrings.

However, I then remembered that my aunt has a gorgeous pair of diamond stud earrings that she is willing to let me borrow - only thing is they are yellow gold. Nothing else I will be wearing will be yellow gold - my ring is white gold and my dress has silver detailing:
So, do you think it would matter that the studs are yellow gold? Will it even be noticeable? If it will be noticeable, should I change the necklace? I paid $80 and it cannot be returned but I could wear a small yellow gold heart pendant necklace that my granddad gave me on the day I was born (that that would be very cute, but still the yellow gold would not "match" my ring or the dress details).
