This sterling silver charm is a 3D thumbs up sign and everyone who went to Texas A&M University knows this is what you do as you are greeting a fellow Ag or when you say Gig'Em (speaking from class of '82 experience). It is about 1.5 cm tall and 1.5 cm wide! Each one is slightly different. Look for the other Texas A&M related items like WHOOP, GIG'EM, HOWDY, AGGIE MOM, OLE SARGE, AND THE THUMBS UP GIG'EM SIGN also in my store. I have rings, bracelets, charms, and can make earrings.
