This museum-quality trinitite specimen is the most valuable piece in the entire collection, distinguished by its exceptional size, composition, and formation. Unlike standard samples, this piece consists of two individual fragments that fused together as they cooled on the desert floor following the world’s first atomic detonation at the Trinity Test Site on July 16, 1945. Its shape and texture clearly reflect that moment—when molten sand, vaporized tower materials, and bomb components rained back to earth and solidified into the glassy relics now known as trinitite.

What makes this specimen extraordinary is its three distinct color zones: green, black, and red trinitite. While common trinitite is typically pale green, the presence of black and red varieties marks this as a highly desirable and uncommon piece.

• Red trinitite is exceptionally rare, created when copper wiring from the bomb’s instrumentation melted and blended with the liquefied sand.

• Black trinitite contains elevated iron and other materials from the test tower structure, giving it its dark coloration.
  Together, these colors—combined in a single fused specimen—demonstrate the complex mix of materials vaporized and reformed in the intense heat of the explosion.

Large, multi-colored, naturally fused specimens like this almost never appear on the market. Its striking appearance and scientific uniqueness make it a centerpiece for any advanced nuclear history, geology, or Manhattan Project collection.

This rare red trinitite specimen is an exceptional piece of material history from the world’s first atomic detonation at the Trinity Test Site on July 16, 1945. While most trinitite is the familiar pale green formed from melted desert sand, red trinitite is a highly uncommon variety, created when copper wiring and components from the bomb’s instrumentation were vaporized in the blast and fused into the molten surface. The resulting copper-rich glass produces distinctive red hues that only occur in a very small fraction of recovered material.

Examples of red trinitite of this quality are seldom seen on the market, and its vivid coloration, strong provenance, and connection to the earliest moments of the nuclear age make it a standout piece for any serious collector. Rare, scientifically significant, and visually striking, this specimen represents one of the most coveted forms of trinitite available today.

This rare large trinitite specimen is an outstanding example of the glassy material formed during the world’s first atomic bomb detonation at the Trinity Test Site on July 16, 1945. While most surviving trinitite exists as small, thin fragments, pieces of this size and integrity are increasingly scarce—especially as legally obtained, well-preserved specimens become harder to source each year. Its broad surface, substantial thickness, and excellent structural stability make it an ideal display piece that immediately commands attention.

Formed when the blast’s intense heat fused desert sand with vaporized components from the test tower and surrounding instrumentation, this specimen exhibits the classic pale green hue and subtle textural features that define authentic trinitite. Its size allows for a clearer view of those formation details, from the glassy surface to the delicate mineral inclusions created in the milliseconds after the explosion. For collectors of nuclear history, geology, or Manhattan Project artifacts, this is a truly exceptional example—rare, visually impressive, and historically important.

AUCTION PRICE: $750

These small, rare pieces of black trinitite are fragments of the world’s first atomic detonation at the Trinity Test Site on July 16, 1945. Unlike the more common green trinitite, black trinitite forms when higher concentrations of iron and other materials from the test tower mix with molten desert sand during the explosion, creating its distinctive dark color. Each piece is a unique artifact, capturing a tangible moment in history in miniature form.

Priced at $125 per piece, these fragments are also available as a set of four for $400, making it easy to acquire multiple examples for display, study, or collection. Small, rare, and steeped in history, these pieces are an ideal introduction to trinitite collecting or a striking addition to a larger Manhattan Project or nuclear history collection.

AUCTION PRICE: $125 each or 4 specimen for $400

These small, rare pieces of red trinitite come from the Trinity Test Site, where the world’s first atomic bomb was detonated on July 16, 1945. Unlike the common green trinitite, the red coloration is caused by copper from the bomb’s wiring and instrumentation fusing with molten desert sand during the explosion, making these fragments exceptionally rare and highly sought after by collectors. Each piece is a unique, tangible remnant of a pivotal moment in history.

Priced at $100 per piece, or four pieces for $300, these red trinitite fragments offer an accessible way to own a piece of the Manhattan Project’s legacy. Perfect for display, study, or adding to a growing collection, they provide both historical significance and visual appeal in a compact form.

AUCTION PRICE: $100 each or 4 specimen for $300

These trinitite pieces are authentic remnants from the world’s first atomic bomb test at the Trinity Test Site on July 16, 1945. Each piece captures the unique glassy texture and mineral inclusions formed when molten desert sand fused with vaporized materials from the explosion.
