3.1" Polished Partial Thunderegg with Colorful Agate
This is a gorgeous partial thunderegg section that has been cut and polished to a glossy finish to display the beautiful red, orange, and yellow hues of the agate. It measures 3.1" wide and is accompanied by an acrylic display stand.
One of the polishers we work with found this material as part of an old collection. The location was not provided and we are unable to determine where this banded agate came from.

About Agate
Agate is a variety of microcrystalline quartz (chalcedony) that displays translucence and, in some cases, banding. Agate primarily forms when silica-rich fluids fill pockets within rocks and/or fossils, depositing the silica along the walls of the rock. This process can result in banding patterns, as the compositions and impurities of these depositing fluids change over time. These banding patterns can either form as flat layers, creating linear patterns known as waterline agate, or as rounded layers, forming more common ring-like patterns. These patterns depend on the surfaces available for deposition.
