This beautiful vintage sick pin has alternating diamonds and rubies prong set on the top. Each of the stones measures approximately 3 mm wide. It is beautifully faceted. The Rubies are a deep red, and the diamonds are a beautiful cut! The backs of each setting are open, and the stones are very secure in their setting. The decorative section measures 1/4" tall. The pin weighs 1.6 grams, and is 2 inches long. This pin would look lovely as a pendent as well!
