Description from the seller
A bubble of air trapped in basalt.
An ancient breath, held suspended under pressure as the lava cooled, slowly, in the darkness.
Thus this cavity was born, a secret chamber of the Earth, where time created crystals, amethyst, the memory of fire.
Purple, gleaming tips, the echo of what used to move, heat, explosion… and then silence.
This geode is the form of an event, of the Arapey Formation, dating to the Early Cretaceous.
A small geological universe, enclosed in stone, a vibration in an impossible balance, between force and quiet, between magma and silence.
During the volcanic activity of that era, basalt lavas solidified, trapping gas bubbles that formed hollow cavities.
Over time, silica- and iron-rich hydrothermal solutions penetrated these cavities and began to crystallize slowly, forming amethyst crystals.
The violet color derives from the presence of iron ions and exposure to natural radiation over millions of years.
