For your consideration is this interesting stick pin. The top has tested as sterling silver and has a genuine coral stone in a great modernistic abstract design. Reminds me of Pal Kepenyes work but is unsigned. The stick pin and clutch itself is not sterling silver.
The stick pin measures 3 and 1/2 inches in length. The top measures 5/8 inches by 1/2 inch.
It is in excellent condition other than minor bending. The coral has irregular nature shape but is 100 percent secure.
