Ph17,
Under normal circumstances I would agree with you full. However, in taking and exerpt from the pendant page:
"This Iced Out Pendant is made of the highest quality Stainless Steel with a Platinum finish for that extra shine."
If this symbol has been around for a millenia, then the possibility exists to create a knockoff jewellery design. Appearantly you can get it "with that extra shine". Hence, the possibility of this aforementioned item potentially being the real deal. Time will tell the tale. We will just have to wait....
