Thanks for the warning - you certainly have eagle eyes! I hadn't noticed it, but it was a hair and I've cleaned it now. Mind you, with two cats and a dog in the house, that's not surprising.
Many thanks for your instructions - I've printed them off and will keep them safe. You might come to regret it, there'll be no stopping me now!
Hi Jacqualina, saw your pics on the Rocks&Co forum, very nice and well done. Just wanted to say privately, on the second pic of the ring on your hand, when its enlarged, I can see something on the lower right part of the stone. Hopefully its just a hair or piece of fluff. Have you noticed it?
