This is a special one!
This naturally etched Herkimer Diamond hosts multiple moving enhydro bubbles that are made of petroleum! The black bubbles can easily be seen moving around when the stone is shifted. The internal and external etchings of this stone are filled with petroleum which react in UV lighting and give the stone a darker color. It also hosts multiple rainbow refractions.
This one has been a secret in our personal collection for a long time and now you know why! It will definitely be an irreplaceable piece!
