Lightning Strikes ~ A close relative of the "Banded Opaque" is the so-called "Lightning-Strike". These very rare marbles are about 1 1/2 inches in diameter and thus a lot bigger than the regular "Banded Opaques". They always have a white base with up to 3 different colored bands (the "lightning strikes") around the equator. Marble experts assume that these marbles were made before the golden marble era in Germany. But their origin is basically unknown.
