Which ancient wonder used chryselephantine construction, combining gold and ivory?

The Statue of Zeus at Olympia used chryselephantine construction, combining gold and ivory.

Chryselephantine statues were made by attaching plates of precious materials to a structural core, often made from wood. Gold represented the god’s clothing and other details, while ivory was used for exposed flesh such as the face and hands.

The statue stood in the Temple of Zeus at Olympia and was created by the sculptor Phidias. Ancient descriptions emphasized its imposing seated form, richly decorated throne and costly materials.

Chryselephantine does not mean the statue was solid gold or solid ivory. The technique was a sophisticated surface treatment over a supporting structure, which helped artists create enormous figures while conserving rare materials.
