"Crafted from 40,000-year old Woolly Mammoth Ivory, they capture the exquisite design and proportions of the original Staunton pattern Chess set, registered by Nathaniel Cook and produced by Jacques of London in 1849"

For more than 2,000 years, Mammoth Ivory has been traded and it remains a highly prized commodity across the world. While that demand for the Mammoth Ivory has always been higher than its supply, it skyrocketed in 1963 when the CITES agreement was enacted. This agreement banned all sales of new Elephant or Walrus Ivory, in an effort to protect the animals from extinction. As a result, Mammoth Ivory became the only type of animal-based ivory that is exempt from the international trade restrictions because it is considered to be a fossil.

The price is $9.995.00.  If that's not offbeat enough for you, try "Endangered Parrots of the World Chess Set," for $4,790.00, although I suspect they would come down if you bought them in quantity.
