All the jewelry is carved green stone. I have no idea what kind of stone it is. It almost looks like green onyx but I am just guessing. They all have a carved face and are very similar. I am not certain if they were a matching set that came together when originally purchased. The bracelet face is quite large. The front measures 2" x 1 3/4". The opening in the back is 1 3/4" and the circumference is 6 3/4" including the opening. The bracelet is marked Sterling. The ring face is quite large also. The front measures 1" x 1 1/4" and is approx. size 6 1/4. There is a little chip on the bottom corner of the stone. It is marked Sterling. The earrings are screw on and measure from the top 1 1/2" x 5/8". I am unsure if the screw part is sterling but the piece with the stone face is marked Sterling. All pieces show wear, tarnish and scratches. A wonderful and unusual set.
