If your luxury car is modern, we'll determine its estimated value by taking into account its year, make, model and overall condition based on market pricing. If it's a classic model, we research specialist car auctions like Bonhams, and also talk to people with their finger on the pulse and steering wheel of the market. This will be followed by an inspection in person, after which we will be able to give you a final loan value.

While this includes everything from a Rembrandt etching to a Jeff Koons rabbit, the principles are the same. We take into account the artist, the uniqueness and provenance of the piece, the strength of the attribution, the supply/demand balance and any data we can locate from auction, gallery, and private-sale records including databases like ArtNet.

Below you will find a high-level summary of how we proceed with appraising jewellery. As jewellery valuation is complex, we encourage you to enquire directly about specific pieces:

The Maker - Whether or not the piece is signed, and by whom. Fine makers like Cartier, Van Cleef & Arpels and Tiffany & Co. add significant resale value

Material – Whether the item is made of white, yellow or rose gold – or – platinum – and its carat weight, are all significant drivers of valuation

Gemstones - If it's a diamond, the famous foursome of clarity, cut, color and carat is central. We use the Rapaport Diamond; it is an internationally recognised guide. Of course, if you have a certification from the Gemological Institute of America, the European Gemological Laboratory, the International Gemological Institute or the Gemological Association, we take those into account. For sapphires, rubies and other precious stones we welcome certifications from the Swiss Gemological Institute and Gubelin

Our valuers combine their own current market knowledge with insights from manufacturer databases, when available; this includes Rolex and Breitling repair centres as well as auction records, from auction houses themselves and third-party data collectors. As part of our diligence we also look for a match with registers of lost and stolen items.
