Ring worn by Adria, and the facsimile of Osric while she had impersonated him. The markings are distinctly Ori in origin, rather than Celtic. This tipped Dr. Daniel Jackson into believing that "Osric" was not who he claimed to be.

KEY EPISODE

The Quest, Part 1 - "Osric" contributes a ring he had been wearing into the treasure chest, allowing all the members of the entrapped quest to be freed from the second challenge. Adria, pretending to be Osric, makes a mistake by allowing Daniel to see the markings of the ring.
