Jewellery
Koller offers a fine selection of coloured precious stones, diamonds, natural pearls and jewellery from all periods, mainly from private collections. Our four annual jewellery auctions offer a wide range of vintage and signed pieces at all price levels.
Some of the well-known makers which are always present in our auctions are Boucheron, Bulgari, Cartier, Harry Winston, JAR, Mauboussin, Tiffany & Co., Van Cleef & Arpels, and Webb. Jewellery has always been considered desirable to own and wear as well as a solid investment, and this is true today more than ever. Our specialists examine and estimate your jewellery from a historical and aesthetic perspective, analyse its value on the current market, considering factors such as its provenance and collectability. Our long experience and intimate knowledge of the market are our guarantee of a professional evaluation of your jewellery as well as the successful handling of its sale. The numerous visitors to our previews in Zurich, Geneva and Germany, combined with our international network of collectors and professionals, assure worldwide interest and exceptional auction results.
Reto Schmidlin, Head of Department for Jewellery, is available to estimate single items or entire collections for our upcoming auctions.
Consignments are accepted until mid-January for our April auctions, late March for our June auctions, late June for our October sales, and late September for our December auctions.

If you wish to consign to one of our auctions, we will value your artworks free of charge. Please send us photos if possible, or call us. We will arrange an appointment to view your property at your home or in one of our offices in Zurich, Geneva, Florence, Munich or Düsseldorf. You will then receive our auction estimates so that you can make your decision.
