4.8" Indonesian Plume Agate Slab - Java, Indonesia

This is a gorgeous, 4.8" wide, polished slab 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 on both sides and polished to a glossy finish on one.

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 rock and/or fossils, resulting in deposition of the silica along the walls of the rock. This process can result in banding patterns as the composition and impurities of the fluids change over time. These banding patterns can either form as flat layers or rounded layers, depending on the surfaces available for deposition.
