This is an astonishing marble made by Joshua Vincent of Vincent Glass Works. This thing is hefty, weighing in at nearly 3lbs. The diameter of this massive marble is approximately 4 inches. The interior of the marble features an amazing geometric bubble pattern made from iridescent fuming. The exterior of the marble resembles a Gas Giant with opaque storms that swirl around a central 'eye'. This would make an incredible addition to any serious glass collection.
