5.2" Indonesian Plume Agate Section - Java, Indonesia

This is a gorgeous, 5.2" wide, polished section of Indonesian moss agate that was collected from Java Island. It features green moss-like formations that branch inward from the walls of the cavity, all of which are encapsulated in banded agate with light-blue coloration. It has been cut flat and polished to a glossy finish on one side, while the outer edges and back of the specimen have been left rough.

It comes with an acrylic display stand.

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.
