There have been quite a few sales of Dorrie's work on Ebay from private sellers as well as Antique and Jewellery dealers, prices have varied from the sensible to full retail. There is always the chance of spotting something that might be by a famous jewellery designer but not recognised as such the same as fuddlng in an antique shop but in the comfort of your own home. See http://jewelry.ebay.com/. The quality of photography on ebay is also extremely varied so can be difficult to see details that might indicate the piece is or isn't by Dorrie.
