My wedding/engagement rings who look similar with these were brought to vendor for free cleaning. After N years of wearing them permanently 'coz I gained weight from pregnancy until I decided to lose weight this year triggered by an elevated blood pressure & lately caused by flu. I lost so much weight when I had the flu 'coz I don't have the appetite & I'm more on fluid intake. Anyways, I was having a shower when I was able to remove my rings. It was awesome 'coz it really meant that I truly lose weight. I wore them since I got married until I gave birth which made it more impossible to remove.
