Fahrner Jewellery

[malpals]

Hi, I have just acquired a Fahrner necklace. I have googled him and although I can see he's a ver reputable jeweller, I can't fin much info about the jewellery itself. There's not much on eBay to compare it to and the pieces that are on some websites seem to be all similar. Does anybody know where i could see more or know whewre i could get a valuation to sell (not for insurance). Thanks in advance.
