From some quick research on the web, it looks like Tiffany copied Harry Winston's business model with regard to investing in diamond mines. It looks like Tiffany is a recent convert to this model, whereas it appears that HW has been investing in the Diavik mine since the early 1990s. It's hard to tell from the timelines, though.
