Aluminu, gold, antique eyeglasses

I am thinking these are from the 30s I am not sure. The name Gaspari. there's solid aluminum glasses but the bridge of the nose is 12 carat...... they are stamped aluminum & 12-carat.. they are in super mint condition super shining the pictures does not do it justice. I am amazed of the quality they were built with That's why they still look this good I guess....... If someone knows what year these are from it would be helpful I am just guessing the 30s .
