<human>: Give me a shortened version of the text

Both early 30s. Both have well paying jobs. Last month my boyfriend proposed to me. I have very mixed feelings about the ring. Since my grandmother died, I have wanted to use her engagement ring and wedding band. Unfortunately there was no diamond in it when I received it.

My fiancé knew I wanted to use it and said he originally took it into the jeweler, but they'd have to cut it to resize it. He was unsure if I'd want to have it cut, so he decided not to use it. Personally I think it had more to do with the cost of placing a new diamond in it. So he instead bought me a new ring.

I know this is a touchy subject for most guys, but I'm an only child and I'd like to use my grandmother's ring to remember her by and not just keep it in the box. He said if I really wanted to change it we could, but he was so proud of the ring he got me. I didn't want to hurt his feelings. 

My grandmother's ring would also require a more expensive diamond, and I don't want to come across as greedy or ungrateful but I know he didn't spend that much on this ring. He spent about a weeks salary on it and it's less than half a carat although it does appear to be good quality.

Is there a way to bring this up and not hurt his feelings or should I just be happy with what he got me? I don't want to come across as greedy or hurt his pride. Suggestions?
<bot>: boyfriend proposed, but I want to use my grandmother's ring that requires a larger diamond instead of the ring he got me. Is there anyway to ask and not offend him? Both early 30s with good jobs.
