I have a thing for galuchat. There. I’ve admitted it. Also known as shagreen, the word’s genesis has an interesting story. Quoth Wikipedia, “Shagreen is a type of leather or rawhide consisting of rough untanned skin, formerly made from a horse’s back or that of an onager (wild ass), and typically dyed green. Shagreen is now commonly made of the skins of sharks and rays. The word derives from the French chagrin and is related to Italian zigrino and Venetian sagrin, derived from the Turkish sāğrī / çāğrī ‘rump of a horse’ or the prepared skin of this part. The roughness of its texture led to the French meaning of anxiety, vexation, embarrassment, or annoyance.”
Natalia Brilli uses galuchat here to form chains for a bracelet. Looking at this piece on the site under magnification, the characteristic dots look more impressed into leather than genuine galuchat, but they do give the piece an interesting texture and iridescence.
