by emeraldgalB » Dec 31, 2012 Hello! Hopefully, I am being overly paranoid, but i thought I would run this by you all. I have an emerald(gemstone) engagement ring, which I only wear on special occasions, as I also have my grandmother's diamond ering. I had read online to avoid drastic temperature changes while wearing my ring(such as jumping into a freezing pool). This led me to think about what is considered a drastic temperature change. Is it safe to go from, say 70 degrees inside temperature, to 30 degrees outside temperature? If not, i guess I will not be wearing my ring in the winter! Thanks in advance.
