Hello, as the title says I need advice for picking out an engagement ring for my girlfriend of 5 years. Recently my grandfather and grandmother, who I am very close with, offered their first wedding ring when they got married. My question is would you accept the ring to propose to her, though the carat size is not that big, or would you opt for a larger size? I love the sentimental value of the ring and I know she would as well, I just want her to feel as special as she makes me feel.
