The Distino cufflinks are made in gold tone metal with a bezel set green stone that looks like it might be marble. The stone has some brown tones in the green. The gold looking metal around the stone has a very small band of mill work and the border detail is a small square with a small circle inside. The same small band of detail surrounds each piece. The length measures approximately 3/4 inch and the width a little over 1/2 inch. It is marked Distino. My best guess is the 1950s.
