Vintage Walter Lampl Sterling Silver Amethyst Mexican Taxco Screw Back Earrings

Vintage Mexican sterling silver and amethyst earrings.
They were made for the American company Walter Lampl who is known more for costume jewelry. I highly suspect that these were made in Taxco. 
The earrings are set with genuine grape amethyst that is natural and untreated or dyed. The stones all have interior inclusions that are characteristic of amethyst. 
They were formed with the repousse technique, are hollow and backed. They have no dents. 
The are screw backs. 
Fully hallmarked on the back. See photos. 
Measure 1" x 1 1/4".
Together they weigh 11 grams. 
I have not cleaned or polished them. They are tarnished. Formerly One Kings Lane inventory.
