I've got a sapphire ring (with 2 diamonds on either side), set in platinum. I've cleaned it a few times by pouring freshly-boiled water into a little pot, adding dish-washing liquid and then soaking the ring for various times, anything from a few minutes to a few hours. I then give it a gentle scrub with a toothbrush and rinse with warm water. I thought that was OK but now I'm worried I may have damaged the sapphire by using boiled water. It *looks* OK from what i can see with a naked eye, but now I'm a bit paranoid! Can anyone chime in?
Thank you in advance
