Also known as a "Carib ax", a THUNDERBOLT is a dark green, almost black, nodular stone shaped like a "celt" that is found, according to Bahamian natives, at the base of dead trees once struck by lightning THUNDERBOLTS may be the rare petrified products of when lightning "electromagnetically precipitates" manganese salts within certain trees at the speed of light
The thunderbolt is represented in heraldry by a twisted bar in pale, inflamed at the ends, surmounting two jagged darts in saltire, between two wings expanded, and usually has streams of fire issuing from the center
