All Nuggets are Pictured or Partially Pictured with a U. Quarter which is 24.5MM in diameter to give you an idea of size proportion. They are guaranteed to be genuine and not man made as we test by sound, torch and scope for authenticity.Each nugget comes with a certificate of authenticity. In November of 2013 I opened up my Gold Nugget store. With thousands of satisfied customers I will continue to strive to provide the highest quality, largest selection and best priced gold nuggets on.
