Also, it may be fun (and useful) to look over group websites like Trocadero. There is probably allot more than you'd find interesting on that site, but it is a good 'directory' of shops some of which are worth looking into. For example, I found Estate Jewels by their posts on Trocadero. And there are other such sites - more or less sophisticated. Names like 'goantiques' and 'rubylane' come to mind, but for some reason I just do not click towards them much. You might want to take a look. Also, the best thing about these might be the shops listed, not necesarily the current (random) merchandise.
