chryselephantine

Made of gold and ivory.

“1885: I drew near and perceived that the light came from a precious stone as big as an ostrich egg, set at the upper end of the alcove upon a little chryselephantine couch of ivory and gold; and this jewel, blazing like the sun, cast its rays wide and side. — Sir Richard Burton, The Book of the Thousand Nights and One Night, Night 17”
