Geological Characteristics and Potential Interior

ThunderEgg agates formed within gas bubbles in acidic volcanic rocks (rhyolites/ignimbrites). The outer layer consists of a rough silica crust, while the core is filled with concentric zones of chalcedony, banded agate, and central crystalline spaces (quartz, amethyst, or opal). Raw material from this location is renowned for its good structural cohesion, which ensures stable surfaces after cutting and polishing.

Information for Buyers

Each 1-kg package is randomly assembled from a selected import batch. Due to the natural characteristics of the deposits, the patterns, banding, and exact internal structure vary in each piece.
