Necklaces and Christmas ornaments made from coin-sized pieces of reindeer droppings have earned a Bloomington, Illinois, zoo nearly $21,000 this holiday season. The Miller Park Zoological Society made about $5,000 selling reindeer-dropping ornaments last year. It added necklaces this year when customers asked if jewelry was available. 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.
