The product is a beautiful specimen of Fulgurite, a naturally occurring mineral that is fused together by lightning strikes in Chesapeake Bay. This unique and rare collectible piece showcases the beauty of nature and the power of lightning, making it a stunning display specimen for collectors of rocks, fossils, and minerals. With its origin in the United States and being a natural, unmodified piece, this fulgurite specimen is a valuable addition to any collection of crystals and mineral specimens. 6 1/2 inches long.  Width 5/8th inch. Not hollow solid. Found on the shores of the beautiful Chesapeake Bay here in Mathews County Virginia. I've had this for years and didn't know what it was.  Thank God for AI. It is identifying this as FULGURITE.  I will weigh when I get a chance. Unusual in that it is smooth rolling around on the shoreline for years.  Non-magnetic. Any questions I am happy to answer.
