Still worthless, because they don't have the paperwork to prove their origin, and don't have the serial number inscribed inside by means of precise laser. Take any one of them to a jeweler and you may be secretly reported for smuggling blood diamonds.

IMO, the registered ones are also worthless, but I don't have the means to counter hundred years of advertising, so this is just IMO, I won't try to prove anything.
