Louis and Max Fenichel made mostly rhinestone jewelry using Austrian rhinestones, which at the time were the best in the world. They hold up beautifully. These baby blue rhinestones are 8mm heart shaped and 4mm rounds. Set in plated rhodium. The necklace is 16" long and closes with a hook. You can add an extender. Every rhinestone sparkles. Marked Fenichel on the back of the hook clasp. Excellent vintage condition. Fenichel was open from 1925 to 1959. The company is not well known, but there is a similar necklace in Inside the Jewelry Box 3 on page 90.
