Authentic Trinitite Green Black Pearl Metal Red - 11.5 g

Trinitite Green Black Pearl with Metal, Red 11.5 g Large Atomic Glass

This large 11.5-gram Trinitite specimen is authentic atomic glass formed during the Trinity test on July 16, 1945, near Alamogordo, New Mexico. Legally collected in 1948, this green-with-black specimen has a large, dynamic, domed pearl with a fascinating front and back.

Trinitite Geological Context and Significance

Trinitite is fused desert sand formed by the extreme thermal and pressure conditions of the first atomic bomb test. This specimen preserves a direct material record of the Trinity test, the July 16, 1945, event that marked the beginning of the atomic age.

Unlike ordinary glass, Trinitite formed in a complex open-air detonation environment that included desert sand, steel tower material, copper-bearing components, indigenous minerals, and rapidly quenched melt. The result is a historically significant anthropogenic glass with distinctive color, texture, and compositional variation.

This atomic glass specimen is especially appealing because it combines large size, green-black visual contrast, and a rare pale pearl-like embedded glass domed structure. The multiple embedded features give the specimen a great visual focal interest and display appeal.

Trinitite Specimen Description

This specimen has strong visual characteristics, as it is a larger piece of atomic glass with rarer, multi-featured appeal. At 5×, it shows green glass, relict mineral grains, reddish/dark-black bleb melt domains, and vesicles, together with metallic waves, within a single field. This specimen exemplifies a record of flash melting followed by extraordinarily chaotic rapid cooling. Numerous round-to-subround black cavities are visible throughout the glass. These are predominantly vesicles, representing gas bubbles trapped as the molten material quenched extremely rapidly. Some grains retain distinct angular outlines, while adjacent material has become glassy, illustrating the exceptionally short heating interval: individual mineral grains experienced markedly different degrees of melting over microscopic distances.

Macro #1 description (this exact specimen): At 5×, this prominent domed pearl-like bleb is a nearly spherical, pale green translucent glass body with a smooth, strongly convex, pearl-like surface. It contains scattered dark inclusions and tiny internal irregularities and is partially embedded within the coarser, granular trinitite glass matrix, giving it the appearance of a discrete glass droplet that solidified in place.

Macro #2 description (this exact specimen): At 5×, this image shows pale green trinitite glass with striking curved, feather-like, metallic flow line textures sweeping across the surface. Near the upper right is a deep, nearly circular dark vesicle or cavity, bordered by smoother glass and scattered pale mineral grains.

Macro#3 description (this exact specimen): At 5×, this area contains irregular melted glassy black blebs enclosed within translucent olive-green trinitite glass, with abundant pale granular inclusions and small vesicles scattered throughout. A tiny vivid red inclusion near the upper right provides a striking contrast against the surrounding green and black melt textures.
