Agate is a variety of chalcedony, which is a microcrystalline form of quartz (SiO₂). It forms within volcanic and sedimentary rocks when silica-rich groundwater slowly deposits layers of quartz inside cavities, cracks, or geodes over long periods of time.
Agate belongs to the trigonal crystal system as part of the quartz family, though its crystals are too small to be seen individually. Instead, agate is known for its smooth texture, durability, and striking layered appearance.
The defining feature of agate is its natural banding, created by rhythmic changes in mineral content and trace elements during formation. These bands can appear in a wide range of colours and patterns, making every slice completely unique.
This agate slice displays the classic characteristics collectors love:
Agate colours can range from white, grey, brown, red, orange, and even blue or green depending on mineral inclusions. The polished finish highlights these variations, making the slice ideal for display.
Because agate is a natural material, no two pieces are ever identical. This specimen is a one-of-a-kind example of Earth’s slow geological artistry.
Agate slices are popular for many purposes, including:
Their durable quartz composition (Mohs hardness around 6.5–7) makes them long-lasting and suitable for handling and display.
Agate is also traditionally associated in spiritual practices with balance and grounding, though this listing focuses on its natural geological and collectible qualities.
This agate slice is a carefully chosen piece, with the listing photo showing the exact specimen you will receive. It is a genuine natural mineral specimen, not a synthetic or imitation product.
Your purchase includes a Certificate of Authenticity lifetime guarantee generic card for added confidence and collectability.
