This is a solid .925 Silver Ring, not a Plated or a Filled Ring. It can easily be resized by most Jewelers without any issues at all! Thanks for your interest.
The flaw is about 1/2 way down the stone. This is a rather normal occurrence in Bloodstone. It has stayed the same since it was set in the ring. So I would bet there could only be a very slim chance of it cracking more. I always track and insure my items in the unlikely event that it might get damaged in shipping.
