So while on vacation, my aunt gave me a ring. Not just an ordinary ring, a ring that once belonged to my great grandmother then grandma,and my mom and now my aunt. Well it's very pretty nothing i thought i would like, its 18k gold and has two small side diamonds and one bigger one. The problem is the larger diamond fell out and has to be put back in,we have the diamond.
Okay sorry long story, so the question is my bf asked me, what if he put a new diamond in it as an engagment ring. Well so i'm wondering would the diamond have to be the same size or could they put a larger one in it, would that mean them having to change the ring??
