A palm tree which grows in the Rainforests of Ecuador produce a nut or seed called
Tagua Nut (Pronounced: Ta qua).

When the seed is harvested, dried, cut & polished, it resembles the finest ivory in texture & color & is slightly softer than  ivory.
(In the late eighteen hundreds up through World War II this ivory nut was used to make some of the finest buttons in the clothing industry.  Some were even used on the U.S. Army uniforms).

The palm ivory nut began a come back because of the slaughter & near extinction of mammal ivory (elephants, etc.)

Tagua is used by artesian's in making jewelry, carvings. They can be woodburned, painted etc.
