Copper/Silver Banded Prehnite Agate
This charming agate not only has some Copper Banding, but two silver flecks. It’s extremely rare to find silver of any size with these agates. One fleck is reveal on the surface, while the other bigger one is located within the transparent Copper Bands as depicted in the picture. When using a bright light, the silver clearly is visible and reflective.
