Expertise and appraisals

You want to be certain that the Swiss art in your possession is genuine? You are thinking about selling some works in your collection? You want to plan ahead and divide your paintings, prints and sculptures fairly between your heirs, but you don’t know their value? You own works of art that you think might be seen as capital investments by the tax authorities, so you need an inventory and a price valuation?

Our services include:

  • Verification and authentication of Swiss works of art
  • Detailed expertise for individual works and evaluations of collections
  • Valuations (appraisals) of one or more works or complete holdings, e.g. for multiple beneficiaries of a will
  • Consultancy on matters of art insurance, on the sale or purchase of art works, or prior to conservation and restoration
  • Presentations and workshops about art expertise and how to price works

Please feel free to contact us for an estimate. We look forward to hearing from you.
