It does sound fake, all right. Does anyone know how it's supposed to work? Is it supposed to be a means of heating the pearl's surface? or vaporizing the dye? Or is there any explanation offered for it?
I found very few references via Google; this was pretty much the only one that wasn't from a retailer:

Fresh water pearls naturally occur in white, ivory, pink, peach and coral. You'll find an amazing range of colors in the markets from silvers and dark grays, electric blues and greens, firey oranges and yellows, and neon purples and lavenders. Most of these colors are achieved using a special laser-dye process common to mainland China and Hong Kong.

Of course, no one (at least no one here) would expect about.com to be a source of accurate info on pearls. But to say that "most" of the colors come from laser dyeing... who told them that?
