I really thought I had the right size and we did check, but my ring spins and slides just a little too much for me. The problem is, it''s January and I''m always cold. Does this really make that big of a difference? Should I wait till the weather warms up and see how it fits before deciding to try and get it sized down a bit? Is it even possible? What exactly could be done to make an eternity-style e-ring a bit smaller, say a quarter size down?
