I’m a little confused as to what size I should get my new engagement ring resized to. Here’s the deal. Back in September my boyfriend and I went ring shopping, and we determined that my ring size was a 5.75, so in December, when he bought my ring, that is what he purchased. Well, now the 5.75 is too loose, almost to the point of falling off. I’m thinking this is because the weather is colder now, and therefore my hand is smaller than it was in the September heat. (I live in Houston, so it gets pretty hot.) So we went to a jeweler to see what size would fit, and it seems like a 5.25 is currently the best size. My concern is when it gets hot again, that the 5.25 will be too small. I know temperature affects the size of my finger, I just didn’t realize it could affect it to the point of half a ring size. A 5.5 is still a little too big, but would this be the right choice? It seems like it will never fit correctly during a certain time of year no matter what I choose.
