Banded Agate Geode Slice (159mm)

This Banded Agate Geode Slice is a polished natural specimen with excellent detail, contrast, and display presence. Measuring 159mm x 122mm x 27mm and weighing 843g, it has a substantial feel while remaining easy to style in the home or workspace.

The polished face reveals one of its most notable features: waterline agate. These straight, horizontal bands formed as silica-rich fluids settled inside the original cavity over time, creating level layers of white, translucent grey, and soft blue-grey. This gives the piece a clean, precise look that contrasts beautifully with the more organic curves of the surrounding agate.

Alongside the waterline formation, the slice also shows fine concentric banding and a crystal-lined cavity filled with small sparkling quartz points. The rough reddish-brown outer rind has been left natural, adding texture and depth against the smooth polished interior. This contrast between the raw exterior, the glossy banding, and the crystalline centre makes the piece visually engaging from every angle.

Display it on a shelf, console, desk, or side table where the polished face can be fully appreciated. It also works beautifully as part of a mineral collection, especially for those drawn to unusual agate formations, natural patterning, and pieces with clear geological character.

Add this Agate Geode Slice to your collection for a polished specimen that combines waterline banding, quartz sparkle, and natural agate beauty in one distinctive piece.

Agate Healing Properties

Agate is often associated with grounding, calm, and emotional balance. It is widely chosen by those who want a crystal that feels steady, supportive, and easy to live with every day.

• Grounding and stability during unsettled times
• Calm focus in workspaces, study areas, or reflective settings
• Emotional balance through a steady and reassuring energy
• Patience and clarity when moving through change
• A peaceful atmosphere in the home or workspace

The waterline banding adds a visual sense of order and measured progress, making this piece especially appealing for those drawn to calm, layered energy.

History & Lore

Agate has been admired for thousands of years for its durability, natural banding, and wide variety of colours. Historically used in carvings, jewellery, amulets, and decorative objects, it remains one of the most recognisable and loved stones in the mineral world.

Geode slices are especially valued because they reveal the stone’s hidden interior. What begins as a rough natural form is cut and polished to show layers, crystals, and mineral growth that formed slowly over time.

Waterline agate is particularly sought after by collectors for its straight, horizontal bands. These layered layers are formed by gravity-driven mineral deposition, giving the stone a precise structure that contrasts beautifully with the more flowing patterns usually seen in agate.
