Green Dragons Vein Agate Organic Stone Double Flare Plugs Choose your desired size! Dragons vein stone is naturally occurring agate/chalcedony stone that is heated and dyed. It is VERY unique and subject to wide variations in color and design. Though no two pieces are identical, we do our best to pair pieces that are very similar. We try to show in our photos the range of designs that you may receive. If a certain look is preferable, or unwanted, please type your request in the "note to seller" section of checkout and we will do our best to accommodate. EVERYTHING we sell is brand new, never worn.
