Slice of Brazilan crystalized Agate on brass base

This slice of agate, from deposits in Brazil, is remarkable for its crystallised core, which forms a sparkling cavity. An almost perfectly round golden line catches the eye, contrasting with the deep brown hues of the outer edge. The successive layers of agate, from brilliant white to warm brown, create a natural harmony.
Agates form in volcanic cavities where silica-rich solutions crystallise slowly over millions of years. This central cavity and its crystals are the result of an empty space left during formation, offering a unique and fascinating texture.
Mounted on a brass base, this piece comes to life when light comes through it (pictures2, 3 and 4). Its transparency reveals hidden nuances and details, offering an ever-changing visual experience.
