I'm going to have to agree with Ebay, thought the only auction I currently see is going at $25 right now because the gem used for his necklace is Swarovski crystal (on the left is the picture included, as well as an idea for a real life representation). Though sincerely, I have a bracelet with the beads just like his necklace, the pendant being one you can find as nearly any craft store (a plastic version).
I hope this helps you at least a little, good luck!
