Since the original Jem models were covered just the other day it seems reasonable to conclude with what the Jems have adapted into. The Jem originated in 1987, but it wasn’t until 1993 that it saw the makeover that set the precedence for most modern Jems as we know them. In fact, when the JEM7 line was introduced only one original model, the Desert Sun Yellow 777, was still in production, and that only had a few years left to its lifespan by then.
