I know. I'm going to go to my local jeweler to see the difference in size. DH wants to get me a 2 CT, which was what he originally wanted to get me when we got engaged, but it was me who wanted to split the 2 cts into 2 pieces (one for the ering and other for the pendant to be sort of different) and also in those days, we would have gotten a less quality 2cts since we were in the process of buying our first home together. Now, he wants me to have a 2 cts for our 15th anniversary...sooner if we find THE ONE. But, no matter what, the original ering will always be my favorite, as it symbolizes our love for each other and life together. And after what you said, I've decided to wear it 'til death do us part instead of giving it to my son. Perhaps make it into an earring and wear the upgrade on my left ring finger.
