?Narwhals, the mysterious unicorns of the sea, live in the Arctic Ocean and grow to about 18' (not including the tusk). The males grow an elongated tooth that spirals out clockwise to form a tusk reaching 9' in length. This ivory tusk has been attributed with the creation of the unicorn legends. Narwhals have been a protected species since 1972 and importation is prohibited. We have narwhal ivory pieces and tusks for sale that were imported in the mid-1900s and are legal to sell anywhere in the U.S. (with the exception of New Jersey).?? See Raw Materials for other pieces.
