This Agate Geode Slice is a standout specimen. Measuring 159.2mm x 122mm x 27.3mm and weighing 843g, it has a thick-cut profile that sets it apart from thinner decorative slices. There is a solidity to it — a genuine sense that you are holding a piece of significant geological material rather than a lightweight decorative disc.
The polished face is where the detail reveals itself. Waterline agate runs across the surface in clean, level horizontal bands of white, translucent grey, and soft blue-grey. These straight formations are created by gravity-driven mineral deposition, in which silica-rich fluids settled in layers over time, producing the precise banding that makes this type of agate particularly valued by collectors.
Alongside the waterline, concentric agate layers curve inward toward the centre, transitioning into a quartz-lined cavity filled with small sparkling crystal points. This contrast between the orderly horizontal bands, the flowing organic curves, and the crystalline sparkle gives the piece a strong visual range. The rough reddish-brown outer rind has been left in its natural state, adding texture and weight against the smooth polished interior.
At 27.3mm thick, the cross-section of the slice is clearly visible when viewed from the side, showing the full depth of the mineral growth and adding a sculptural quality that thinner slices cannot offer.
Display it propped against a wall on a console or shelf, or incorporate it into a mineral collection where its size and presence can be fully appreciated alongside other specimens. It also works beautifully in styled interiors where natural texture, geological character, and a sense of considered curation are part of the aesthetic.
Add this Agate Geode Slice to your collection for a polished specimen that combines substantial form, waterline banding, and crystalline detail in one genuinely impressive piece.
