This is a great set I recently purchased – I just love how its so dimensional and so well made. Both the necklace and the bracelet are adjustable, a style feature Monet used throughout the 1950s on many of their necklaces and bracelets. The pin for the series is shown in the book and can be found on page 115. The attention to detail on all of these pieces is just outstanding and the quality still holds up after 59 years !!!!!!
Just for reference here is the original mat page for the series from the Fall 1953 catalogue.
