I believe these are filled with pink gold. it has a 10 marking that is difficult to read but you can see for yourself in the last picture.  I found the same mark on other glasses advertised as GF. These have a really nice Art Deco Style engraving on the edges.

Excellent condition. Sorry no case with them. fresh from a NH estate.

Some light Wear. Lenses are mild Rx for reading.

The frames are 4 inches wide - the round glass is around 1 5/8 inches and 

the ear piece is 4 inches before the curve. Just under 4 1/2" wide for your 

face adding in the extensions on the sides.
