Trinitite New Mexico SM 7-9g

Trinitite .7 to .9 grams Authentic Glass from the First Nuclear Test in 1945

Own a piece of atomic history with genuine Trinitite, the rare and collectible green glass formed during the world’s first nuclear explosion. Trinitite, also known as atomic glass or Alamogordo glass, was created on July 16, 1945, during the Trinity Test at the White Sands Missile Range in New Mexico, marking the dawn of the Atomic Age.

What is Trinitite?

Trinitite is a man-made natural glass, formed when the intense heat—estimated over 8,000°C (14,400°F)—of the nuclear blast melted the desert sand. The molten material fused with elements from the bomb’s components and cooled rapidly into a unique, glossy green glass. This newly formed mineral remained scattered across the test site and is now a rare Cold War relic.

Key Features

• Authentic Trinitite from the Trinity Test Site, New Mexico

• Formed during the first atomic bomb explosion, July 16, 1945

• Distinctive olive green to gray-green color

• Composed primarily of silicon dioxide, with traces of feldspar, quartz, calcite, iron, and radioactive elements

• Naturally mildly radioactive—safe for handling and display

• Available in rough fragments, polished specimens, and display cases

Scientific Composition

• Main elements: SiO₂ (silica), Al, Ca, K, Fe, Cu

• Trace elements: Uranium, cesium, and isotopes from the detonation

• Color Variations:

  • Green Trinitite – most common

  • Red Trinitite – contains copper from detonator wires (rare)

  • Black Trinitite – may contain more iron or bomb casing residues

Why Trinitite is Valuable

• Historically significant – direct physical evidence of the first nuclear weapon test

• Legally obtained – collected before the site was declared off-limits in the late 1940s

• Highly collectible – sought by museum curators, nuclear history collectors, and mineral enthusiasts

• Limited supply – it is no longer legal to collect Trinitite from the test site, making existing pieces increasingly rare

Trinitite Price Per Gram

• Common green trinitite: ~$20 to $50 USD per gram

• Rare red or black trinitite: Can exceed $100–$150+ per gram

• Pricing depends on color, shape, clarity, and whether it is uncut or mounted for display
