Designed in the years 1895-1897, this floral and foliate hat pin composed of opal, diamonds and enamel was created by Ren Lalique, Paris. The pin is designed as an opal flower or bud with rose-cut diamond fringe among curling tendrils with en plein enamel shading from cornflower blue to sea green, mounted in 18K gold. Representative of the exquisitely-made and sensitive art of this select period in the artist's oeuvre, this rare work adds significantly to any collection of Lalique and/or Art Nouveau jewelry.
