I used to like R&C (until the prices went berserk), but eventually I got rather bored of shopping channels. As a result, I hadn't visited this forum, or looked at Rocks & Co, in years--until now.
I was shocked to read that it had apparently closed (without my even noticing!), but evidently it must have opened again! It definitely exists, as I was watching it today. The website is still rocksandco.com, although it is broadcasting the German channel Juwelo, with German audio (which is a challenge with my 'O' Level German from 40 years ago!).
I don't think I will be spending much time with the channel now, but it is worth the occasional visit. A lot of the jewellery was dull and overpriced (mostly in silver these days); but I did manage to buy a vermeil enamelled art nouveau-style hair pin in the live auction, which was a very pretty and highly unusual piece.
