New to the Grit workshop! This particular plume variety from Western Java, Indonesia showcases a Milky white,to translucent chalcedony backdrop with creamy beige plumes and black, branch like Dendrite formations. Plume agate forms in hydrothermal environments, where hot, silica-rich fluids circulate through volcanic rocks. These fluids dissolve silica and other minerals and deposit them in cavities or voids in the rocks. Over time, the deposited silica accumulates and recrystallizes, forming layers of chalcedony. The plume-like inclusions are formed when trace minerals in the hydrothermal fluids mix with the silica during the recrystallization process. The coloration depends on the specific trace minerals involved. Please allow for +/- 0.25mm discrepancy as these are all hand made pieces of art. 0g / 8mm round, double flare plugs 11mm thick. 9mm wearable. 10mm front flares. 9.5mm rear flares.
