You can certainly sell the ring if you like, though I'd recommend washing it three times in cold water with a little salt in it, and then leaving it out in the sun for a while, so the purchaser is spared any lingering energies. (You're more vulnerable to those because of the blood connection with your parents.) Delighted to hear about the source for aquamarine -- something like that would guarantee good clean energies.
