It is possible concerning both questions. It ain't easy, but its possible.

I know why you are concerned. Slab a brasscore counterfeit chip that the so-called expert graders encapsulate and you can't see the chip edges to determinne if it is a counterfeit chip. You won't know until after you've spend large dollars for a fake that their so-called experts won't be THE experts needed to provide such a service!
