What we’re asking for the stone is for somebody to go out and spend the equivalent of 280 Lamborghinis. And I use that as an example because I don’t think people quite understand the quantum of money we’re looking at here. And what you’re buying is something for which you’re going to have to rely on expert opinion to give you the full details of what you can expect on the stone, without really knowing the full outcome, the quality. We do have one or two options [to sell it]. If that doesn’t pan out, I think most [surely] within the next six weeks to eight weeks, we’ll most [likely] look to enter into a partnership.
