Death Valley Plume Agate, also known as "Wingate Pass Agate", is a relatively rare, colorful variety plume agate that came from Wingate Pass in Death Valley, California. Agate from this location was collected prior to Death Valley becoming a national park, therefore specimens on the market are purely from old collections. This makes finding uncut, rough material difficult due to the majority of available specimens already having been cut and polished.

Agate is a variety of microcrystalline quartz 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.
