Material in walrus tusks

IVORY

This hard, creamy substance was once prized in piano keys and carved art.

Walrus tusks are made of a hard, dense material called ivory, which is the same substance found in elephant tusks. The clue is straightforward—it directly names the material without any wordplay or hidden meanings. Ivory has been historically valued for carving and decoration, though its use is now heavily restricted due to conservation laws.
