From Wikipedia, the free encyclopedia

Adamantine is a veneer developed by The Celluloid Manufacturing Company of New York City, covered by U.S. Patent number 232,037, dated September 7, 1880. Seth Thomas Clock Company purchased the right to use the adamantine veneer in 1881. This veneer is sometimes referred to as celluloid and is found on clocks in a wide variety of colors that simulate marble or alabaster.
