Shagreen

a kind of leather produced originally by oriental people from the hide of the horse, camel, or particularly of the ass. Sometimes the skin of the shark, sea-otter, or seal was substituted. In tanning the seeds of a species of goose-foot are embedded in the soft skin. The skin is then shaved and soaked. The pits in which the seeds lay swell up into relief, giving a peculiar granular appearance. The finished leather is dyed a rich green by a compound of sal-ammoniac and copper filings. Shagreen makes a luxurious binding for books and is used for expensive upholstering. The name is Turkish, meaning the back of a horse. See Leather
