It forms in clusters that often resemble bunches of small grapes, and colors can range from pale to deep purple to green. Some specimens can be quite sparkly due to minute quartz crystal growing on the spheres. Grape Agate is a relatively new material on the market, first being exported from Indonesia around 2015.
