This is a beautiful necklace from the 20s. It may be sterling silver … we did not have it tested. It has the French design of 20s. The centerpiece has a triangular camphor glass connected to links with alternating blue cabochon glass stones and silver decorative links. It is signed but can’t read it properly. It has a spring back clasp and measures 15” long. The camphor is 1-1/2” wide x 1” long. It’s in excellent condition.
