Warehouse 13, Excalibur Defense Stone

original movie prop

Early in second season episode Age Before Beauty, Pete and Myka are in Cardiff, Wales, trying to recover no less than the sword Excalibur. In doing so, they use this rock infused with the same metal that gives Excalibur its magical qualities, and that causes the otherwise invincible sword to phase shift when the two come in contact.

Hard but lightweight textured resin rock, painted red-orange, with sculpted veins of a silvery metallic hue, and grey weathering. Pattern of veins and color variegation can be screen-matched to the scene where Myka holds it up to defend herself from Excalibur.
