--Previous Message-- : : Lorenzo - I am totally intrigued by all : this. : : I do hope the archive will be able to give : you the original information about the : piece. : : I will stick my neck out and suggest that : the tiny spiral is to set an element en : tremblant . : And that some original elements might now be : "lost". Perhaps they are now with : the original frame.
I think the only missing elements are the frame and the screws.
: The current necklace does not look like one : continuous strand but four short lengths.
Around the central brooch/pendant there are four semirigid elements, the mobile part of each is the diamond drop.
: And the inner two lengths seem to have : something unusual in their middles - or is : that just a quirk of the pic?
You are correct, the middle elements have a twist, quite strange in the picture, but not bad to see in real.
: Edit: the central element looks like a : brooch/pendant so perhaps the longer chain : was for wearing it as a pendant.
Very likely. The only surviving screw is the one that keeps the brooch in place: you can see it on the picture of the reverse of the necklace, its head has a flowerlike shape and it fits perfectly in the cavity of the screwdriver.
: And I'm further intrigued that you have the : case plus tools! :
