It is just a clever name for a CD case. They are the slimmer version of the standard CD case. "Jewel" refers to the piece that clips into the center hole of the CD to keep it in place. It has a jewel-like design.
CD jewel cases are made through a process called injection moulding
The black, polypropylene DVD cases are called, well, "DVD cases." Sometimes, they are also called "Amaray cases" because Amaray was the first manufacturer. The clear, polystyrene CD Case is called either a "CD Case" or a "jewel case." The term "jewel case" is attributed to the packaging designer Peter Doodson, a Dutch designer, who worked for Philips.
A digipak has the size and look of a CD jewel case but it is made of paper stock with a plastic tray glued to hold the CD. With a typical clear tray, a digipak has 4-panels for putting the artwork on. One advantage of digipak over jewel case is that it has better shock absorption than jewel case. When a jewel case is dropped it breaks. But a digipak will still be in one piece even it is dropped. A picture is worth more than a thousand words.
