It has nothing to do with the movies. And gold doesn't do jack diddly for protecting from being cursed if bitten, or from Enthrallment. But don't believe me. Wear a gold necklace instead of Sterling Silver necklace. See what happens to you (nothing good.)

I'll say it again: You need to be wearing a STERLING SILVER NECKLACE IN ORDER TO NOT BE CURSED, IF BITTEN (CAUSE IT'S A NECK BITE) OR ENTHRALLED. WEARING A GOLD NECKLACE WILL NOT PROTECT YOU. A PURE SILVER NECKLACE WORKS TOO, BUT IT'S NOT NEEDED. ALL THAT'S NEEDED, AGAIN, IS A STERLING SILVER NECKLACE.
