Can NGC's metallurgical analysis determine the composition of a medal inside of a "slab", that is, a silver ring with glass lunettes?

Thank you for the question. We would only be able to do a metallurgic analysis if the coin was taken out of its holder. The machine cannot test through plastic or glass.
