This material was collected long ago by Ralph Pray and the order is for 5 grams of random Trinitite pieces. Sample orders as pictured. 20 dollars a gram for these larger and more attractive specimens is wholesale cost and leaves plenty of meat on the table for shows and resellers of this classic and historic material.
Limited quantity of material so stock up while you can!
Trinitite (also known as atomsite or Alamogordo glass) is a glassy residue created by the world's first nuclear explosion, the Trinity test, on July 16, 1945, in New Mexico. 
Key Characteristics
Formation: It was created when the Manhattan Project's "Gadget" detonated, vaporizing the surrounding desert sand, the test tower, and the bomb casing. This molten material then "rained down" and solidified into glass.
Appearance: Typically a light olive-green color with a porous, "frothy" texture. Rare variants include red trinitite (containing copper from the bomb's wiring) and black trinitite (containing iron from the tower).
Composition: It consists primarily of melted arkosic sand (quartz and feldspar) fused with traces of plutonium, americium, and other fission products.
Radioactivity: While it remains measurably radioactive, it is generally considered safe to handle and display today, as many of its most dangerous isotopes have decayed. However, it should not be inhaled or ingested. 
Legal Status & Availability
Site Protection: In 1952, the U.S. government bulldozed and buried most of the trinitite at the Trinity site to discourage souvenir hunters.
Collection Ban: It is currently illegal to remove any material from the White Sands Missile Range (where the site is located).
Private Ownership: It is legal to buy and sell trinitite that was collected before the 1952 ban. Authentic specimens are highly prized by collectors of atomic-age artifacts.
