In recent years QVC have had at least two very similar South Sea Pearl necklaces from the look of the pictures SCW found, I know because I ordered one of them (it was around £600) and returned it, and later contemplated ordering the other (around £900 I think). I would have thought it likely that what appeared in the Outlet was the last remaining stock of one of these lines (or perhaps the sample used on-screen, the Outlet staff once told me they receive all the samples after shows, that's why they have tons of rings in sizes J, K & L as that is what most of the female presenters take!)
