These beautiful specimens are approximately 2 3/4" to 3" on each side, and are 2" thick. They were irradiated through one of the large flat sides, rotated 180 degrees, and irradiated again through the opposite face to create two parallel layers of charge about 1/2" below the surface of each face. Depending upon where and when these charge layers were discharged, complex electrical interactions were created between the two charge layers. This caused a variety of unusual, and very spectacular, discharges.  Although many of our other Lichtenberg Figures form simple 2-Dimensional planes, these figures are truly 3-Dimensional. They contain not only branching discharges within each plane, most also contain complex interactive discharges between planes. Some of these specimens look like a time lapse photograph of a raging lightning storm, while others are similar to African Acacia trees. Other sculptures have plane-to-plane discharges that resemble sprites or gigantic jets, rare forms of high-altitude lightning), that can appear above powerful thunderstorms:

Some sculptures have two virtually independent parallel discharge planes connected only by a single discharge root. Some exhibit branched dendritic discharges, others have "snowflakes" (small tuft-like discharges that resemble individual snow crystals), while others are wildly chaotic with seemingly random fluffy "cotton-candy-like" discharges. Many specimens show various combinations of dendritic, chaotic, and snowflake discharges. Although the internal patterns vary from specimen to specimen, we guarantee that you will be fascinated and satisfied with your purchase.
 
These specimens were created from blocks of high quality, crystal-clear cast acrylic. The following images do not begin to capture the depth, clarity, and jewel like character of these 3D figures. When illuminated by a multicolor or rotating LED base, these become sparkling treasures of scientific art. Laser crystal art can't begin to match the exquisite detail, intricate complexity, and infinite variation of the fractal discharges within these prisms. Newer specimens may also exhibit solarization - amber colored layers between the irradiated surfaces and the discharge. Solarization layers may also fluoresce when illuminated by blue or near-UV LED's. Solarization, and its associated fluorescence, usually disappears with time.

Please select which type(s) of discharges you prefer (i.e., African Tree, Windblown Lightning, etc.), and we will try to find one that matches. Some styles, such as "Heavy Weather", underwent multiple discharges while being irradiated by the electron beam. This caused repetitive discharges that created a bit of darkening of the main discharge paths which adds a different character to the piece.  The darkened areas disappear once the specimen is illuminated. However, some customers may find these specimens less appealing.  Rest assured that your satisfaction is always  guaranteed by Stoneridge Engineering. If you are not satisfied with your purchase for any reason we will gladly offer to replace your item or provide you with a full refund!
