This 2 & 1/2 by 1 & 3/4 inches enamel brooch of red grapes is probably of American vintage, early 20th century, though it is only marked sterling. Probably Watson or Robbins was the maker, but it is only my surmise based on similar green and purple grape brooches by Watson and Robbins. Whoever made it, it is a top quality piece of enamel on heavy gauge silver in excellent condition.
