Four (4) of the ring blanks are gold-colored and the round pad is 23.7mm.

Two (2) of the ring blanks are silver-colored and the round pad is 24mm.  

They are not real gold or silver but are brass.  I purchased them personally from Rio Grande.  I was making rings by gluing vintage earrings with the backs removed to make pretty rings but am no longer doing that.  (I have a listing of earrings with the backs removed that I prepared for this project).

Come from non-smoking home.  Final sale.  No returns.  Please inspect all photos and ask all questions prior to purchase.  I am happy to combine shipping.

Thank you for looking!
