These are specimens of Trinitite, glass formed from the earth when the Trinity nuclear test was conducted, marking the beginning of the nuclear age. They aren't radioactive anymore but each is a small piece of history. They have a very unusual and distinctive appearance with a green color and odd grainy structure, and their shape reflects the force that formed them. Trinitite is no longer available for collecting so all that's available is what's in old stock and collections--we got these from a friend of ours in the mineral business. They range from about 0.3-1g. These were originally from the Ralph Pray collection. In 1951, before the US Government bulldozed the site and banned further collection, he gathered over 2000 pounds of samples across several visits to the Trinity site. Each specimen is numbered and individually photographed.
