During the Valentino ring segment, historian Gary Dennis erroneously claims that a cat eye's stone is sometimes called "tiger's eye". This is incorrect, they are two different crystals. A cat's eye is not only chatoyant, but also has a a line crossing the center of the stone. More often than not, in contemporary times, they are synthetic stones. A tiger's eye is always natural (as it is too cheap to bother to create simulations) and is a dark orange-brown stone with bronze stripes. Tiger's eye crystal (or gemstone) is also chatoyant but cat's eye is more expensive, particularly if a natural stone.
As per his script, Don Wildman narrates that many fans committed suicide out of grief, after Valentino's death. In reality, this was debunked as being the studio's cash machine trying to draw interest for his final film, Son of the Sheikh, which had yet to be released in 1926. No fans would have committed suicide, not even the famous woman who would have left a suicide note. It was fabricated, as was later revealed.
