A silver 'oyster and pearl' in silver with onyx 'pearl' designed for Georg Jensen by Nanna and Jorgen Ditzel. 

The chain is un-hallmarked - owner is the daughter of the director of Georg Jensen so some items had been made but not sent to the assay office -  

Vintage - 1960s - and in excellent used, sound condition. Postage includes insurance.

Listing more antique/vintage Danish jewellery from this collection over the next few weeks, including one very important prototype piece, so save me if you're interested! I combine on postage.
