This bracelet includes real meteoritic fragments from the K-Pg boundary layer (Chicxulub Impact Event)!

"Impact of a large earth-crossing asteroid would inject about 60 times the object's mass into the atmosphere as pulverized rock; a fraction of this dust would stay in the stratosphere for several years and be distributed worldwide. The resulting darkness would suppress photosynthesis, and the expected biological consequences match quite closely the extinctions observed in the paleontological record."

~ Dr. Luis Alvarez and Dr. Walter Alvarez, "Extraterrestrial cause for the Cretaceous-Tertiary extinction." Science 208.4448 (1980)

The large-scale geological event known as the End-Cretaceous Mass Extinction had a profound influence on life on our planet. Three-quarters of all life on Earth perished during this time, from marine invertebrates like the ammonites to the large avian and marine reptiles which had held their dominant place for so long, and of course the dinosaurs. In a geological instant, hundreds of non-avian dinosaur species, the product of more than 175,000,000 years of evolution, completely disappeared from the Earth.

Of the leading causes, the Chicxulub Asteroid Impact (c. 66 million years ago) provides a dramatic exclamation point to the end of the Mesozoic. At a minimum, the Chicxulub impactor was 6 miles (9.6km) in diameter, and the energy released likely exceeded more than 100 million megatons.

Evidence of massive fires and mega-tsunamis traced to this event have been found in many areas of the world, as well as a fine layer of the element Iridium which is known today as the K-Pg Boundary Layer. The discovery of this global layer and the eventual hypothesis is credited to Nobel Laureate Dr. Luis Alvarez and his son Dr. Walter Alvarez.

This bracelet includes a custom sterling silver bead resembling a small asteroid. We've carefully embedded K-Pg Boundary Layer samples from North American deposits into the largest recess with high-grade, clear epoxy. Additional dark crevasses provide contrast for the asteroid surface design and reflect the hand-polishing each bead undergoes.

The remainder of the bracelet is comprised of polished, black obsidian beads for a refined look that is beautiful solo but pairs well with our Asteroid Belt Bracelet or other treasures you may already own.

The full bracelet measures 7" in length (~17.5cm) though it will stretch a bit further. If you need a larger or smaller size, please let us know. We can make a custom version just for you. As pictured below, the bracelet works well for men and women.
