The internal world never fails to amaze, as witnessed by this incredible video of a negative crystal in a Sri Lanka sapphire.

Bubbling Up • Carbon Dioxide in Sapphire

Each time we place a gem into the microscope, we look with the eyes of a child, not knowing what to expect. That was certainly the case with this Sri Lankan sapphire that held a real gem inside, a negative crystal containing a microscopic amount of the original broth, the witches brew from which it grew.

Fillet of a fenny snake, In the cauldron boil and bake; Eye of newt and toe of frog, Wool of bat and tongue of dog, Adder's fork and blind-worm's sting, Lizard's leg and owlet's wing, For a charm of powerful trouble, Like a hell-broth boil and bubble.  William Shakespeare, Macbeth
