This choker is perhaps one of the most elegant pieces by the artist in the Gulbenkian Collection, for despite its apparent sobriety and absence of colour, it presents a truly prodigious combination of technique and supreme artistry. It is made up of a series of small engraved rock crystal squares, alternately decorated with cats and foliage, linked by gold mesh. The joints enabling the squares to flex are concealed by small diamonds, and the top and the bottom of the choker have a gold border enamelled in white.

This extremely sober piece reveals the play of light and transparency that the artist cultivated throughout his life, particularly through the use of glass in his jewellery. In this case, the same effect is achieved with rock crystal, an extremely difficult material to work. The stylistic evolution of the artist is noteworthy in this piece where the dominant lines are rectilinear as opposed to the more sinuous forms of Art Nouveau.
