How could you set a stone like the R3122 and minimize the booger?

Would a gold bezel and white halo tend to hide its problem or emphasize it?  That is such a lovely stone and at such a price I know she won't last long.  Still, for future reference I'd love have an idea of how to take advantage of such a bargain.  (and yes, right now I'm in split shaft heaven, with or without halos)

In a sense it's the same as a "window closing" problem: if you have a coloured stone with a window, it's often possible to place a little "mirror" of gold or platinum to "close" it from many viewing angles.

If done right, it seems almost miraculous: the mirror just reflects the stone colour back while remaining invisible - it effectively turns the "see through" effect of a window into the semblance of a perfectly cut stone. If done poorly - blech.

Here what you need is to reflect a "healthy" piece of diamond rather than the booger. However it ain't simple to do; sophisticated light-modelling CAD might help, but it may push the price of the ring beyond commercially viable levels.
