Zip necklace by VCA

vca_zipper_60000“Sous le marteau” came one of Van Cleef & Arpels most iconic necklace. The Zip necklace. It saw the light in 1951 after many years of innovation. It was the Duchess of  Windsor who came with the idea to design a piece of zipper jewelry. The Zip necklace has a small device that is used to zip and unzip the necklace. Open it was worn as a necklace and closed as a bracelet. According to the auction house Leclere a few rubies were replaced by diamonds and the necklace needs to be revised. Although when I asked about it, the expert could still unzip the necklace. A truly beautiful piece of jewelry. VCA made several models in diamonds and in colored stones. Only a few came to auction in the last 60 years. Oh and the hammer price? 66.000,- euros.

Empire State Building in gold

Georg Hornemann's Empire State building

Ring from Georg Hornemann master gold smith.

A very special ring goes under the hammer today of German master goldsmith Georg Hornemann (75). It is the Empire State building in gold, diamonds and amethysts. I wonder if this will be the X-mas gift for a rich New Yorker, maybe an architect’s wife? The ring is estimated for 5000 to 5500 euros.

Georg Hornemann has together with his also award winning son Alexander Hornemann a workshop in Düsselfdorf, Germany. Georg Hornemann is the only person to date to receive the platinum guild international award for excellent jewellery design. He works together with international artists and makes besides extraordinary jewelry, objets d’art.



After a day browsing online and real life auctions in Europe, I always learn such a great deal and I thought it would be a great way to share my experiences via this blog. Of course my main subject is jewelry; signed and non-signed pieces from 1940-‘50-‘60.

A 1950/1960 diamond and enamal palmtree clip made by the House of Boucheron

This 18K white gold and platinum Boucheron “clip de revers” from the 1950’s doubled its appraisal in no time. From 2000 to 4500 Euros in one minute. The thing is that this clip misses a lot of enamel on one of its leaves.
Exotic flowers and trees like this palm tree clip were popular designs of the 1950’, but also exotic animals like paradise birds were one the themes to capture in gemstones often in combination with enamel. This clip has a brilliant trunk and baquette diamonds and green enamel for the stems and leaves.

Very heavy braid bracelet

In the same French auction a 1950 bracelet doubled it’s price. This bracelet weighs a whopping 112 grams. The bracelet is a very thick braid of 18K gold with a platinum clip set in diamonds with a tassel. A typical design of that time. Auction result: 4.500,- euros.
