5.45" Polished Cathedral Agate Slab - Gorgeous Purple Bands
This is a gorgeous, polished "cathedral agate" slab that was collected from Chihuahua, Mexico. It features a vibrant mixture purple, orange and red coloration. Both sides have been cut flat, with one side being polished to a glossy-finish. A unique characteristic of these cathedral agate specimens is the occurrence of stalactitic formations which can be seen in this specimen. They can be identified by the rounded ends which would have been facing downward in they cavity they formed in.
It comes with an acrylic display stand.

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.
