This mint, unused, antique silver color metal necklace is a reproduction of the Stargate as seen on the hit sci-fi TV series Stargate Atlantis. It features the locking mechanisms and glyphs and the ring measures 1.375″ across, with a 24 inch chain. It is very similar to the SG1 necklace except that the glyphs on the gate are different. This is a double sided necklace with the glyphs on both sides. It is stored in a smoke and pet free environment.
