Brazilian agate slice (365g.) on a black base

This slice of agate, extracted from Brazilian deposits, features a bold alternation of black and white, creating a striking and captivating contrast. The irregular black border frames the flowing patterns and vibrant shades of white in the centre, evoking an abstract painting shaped by nature.
The heart of the piece is marked by lighter areas, providing a striking contrast between the translucency of the inner layers and the opacity of the border. This phenomenon results from the crystallisation of silica in volcanic cavities, where the layers have formed slowly over millions of years.
Mounted on an elegant black base, this piece reveals all its complexity and beauty when illuminated.
