These armbands were sold in a lot as common Roman jewelry. However, as you can see on the screen captures, they were in fact worn by Gaia, played by Jaime Murray, in multiple episodes of the prequel. They were also used in some publicity photos for the show. Since this is the only set of armbands like this that was sold by VIP, I like to think they are the "real deal" and were worn by Jaime. ;-)
