The Hohokam people primarily used these large Glycimeris shells to make bracelets and rings; the center of the shell was generally removed immediately after the bivalves were collected, and before transport back to the Hohokam villages in the Gila Basin.
There are several scholarly journals which have articles dealing with shell trade in the American Southwest which mention the Glycimeris shell.
