The reindeer droppings are dehydrated, sterilized and spray-painted with glitter. They're called "Magical Reindeer Gems."
The ornaments cost $7.50 at the zoo's gift shop or $10 by mail. The necklaces sold for $15 at the gift shop, or $20 by mail.
The zoological society says the ornaments and necklaces sold nationwide. Requests also came in from other countries, but federal regulations don't allow reindeer droppings to be exported.
