About The Atelier Index

The Atelier Index was founded in London to bring institutional price transparency and rigorous archival serial format inspection to the British pre-owned luxury handbag market.

Every week, thousands of UK collectors, personal shoppers, and consignment buyers inspect pre-owned pieces across eBay UK, Vestiaire Collective, Knightsbridge showrooms, and private sales. Historically, buyers had to piece together fragmented forum threads to decode a Louis Vuitton factory tab or Hermès blind stamp, while guessing whether a seller's £4,800 asking price represented fair value or a 25% markup.

Our Four-Domain Network

To serve collectors at the exact moment they research a stamp or valuation, The Atelier Index operates an integrated UK domain network resolving to our central workbench at https://theatelierindex.co.uk:

  • theatelierindex.co.uk (and defensive international domain theatelierindex.com): Our flagship UK Luxury Handbag Price Index, 10-brand designer archive, and Under-Market Arbitrage Desk.
  • bagdatecode.co.uk: Direct high-intent gateway for decoding Louis Vuitton, Christian Dior, Celine, Gucci, and Saint Laurent workshop date codes.
  • serialvault.co.uk: Direct gateway for checking Chanel hologram serial series, Hermès blind stamps, Mulberry Somerset brass fobs, Bottega Veneta tags, and Prada factory numbers.
