Created circa 1907-1908 by Ren Lalique, this charming mice or "souris" brooch is composed of diamonds, platinum, enamel and pressed glass. On each curling end of a line of choice old diamonds, mounted in expertly -joured platinum, perch crystal mice with enamel tails. A subtle study in whites, this imaginative brooch by Ren Lalique blends precious and ordinary materials of contrasting textures, both visual and tactile.
