Great design, texture and form on this sterling and chrysoprase ring by Modernist jeweler Jules Brenner. Brenner had stores in New York and Provincetown, MA. and early in his career worked with Ed Wiener. This ring is a size 6, is 1 1/8" long, weighs 10 grams, and in fine original condition. The stone is a great pop of color. Signed as shown. A wonderful mid-century piece by one of the great Modernists.
