• PROVENANCE
  'The Magnificent Jewels of Mme Hélène Beaumont', Sotheby's Geneva, May 18, 1994, Lot 522.
  
  Although the bracelet is unmarked, it is recorded in the Van Cleef & Arpels' archive as number 44724 and as being composed of 107.25 carats of rubies and 16.70 carats of diamonds. Van Cleef & Arpels has confirmed that it left the workshop of Rubel Frères on 10 April 1936 and it was purchased on 14 May 1936. The lack of signature, number and Rubel Frères' maker's mark is probably due to the bracelet being altered at some point before it was sold at the Sotheby's auction in 1994.
